1. NASCAR honors victims, heroes of Boston Marathon explosions
Just as it did after the large-scale attacks of Sept. 11, 2001, NASCAR will serve in the role of honoring those affected by Monday's horrific events at the Boston Marathon. Beyond the expected emotional pageantry of Sunday's pre-race ceremonies at Kansas Speedway, two Sprint Cup teams with unique ties to Boston and its annual road race have even made plans to recognize and support the victims and heroes in various ways.

Roush Fenway Racing, the NASCAR venture tightly partnered with Boston's Fenway Sports Group, will carry a unique "B-Strong" decal on each of its cars this weekend. Team owner Jack Roush has also pledged to donate $100 per lap led by his team to relief efforts in Boston. Fenway Sports Group, of course, owns the Boston Red Sox, Fenway Park and other Boston sports enterprises.

Meanwhile, Michael Waltrip will recognize his personal tie to the Boston Marathon by having each of his Michael Waltrip Racing Toyota's sport car numbers this weekend in the same font as the marathon's bib number system.

“The news coming out of Boston this week was very personal to me,” said Waltrip. “When I ran the Boston Marathon in 2000, I remember thinking about what a privilege it was to be able to participate and all the hard work it took to be there. When you can see those international flags flying in Copley Square, you know you are about to complete your journey. I know the joy those runners were feeling at that moment when their worlds changed."

Undoubtedly, expect many in the garage to be sporting Boston Red Sox gear, too.

2. Streaking Kyle Busch hopes to avoid 2012 mistake
This season, when Kyle Busch has found the lead, there's been at least two times in seven races when he hasn't looked back. In three others — now good enough for a career-best streak — Busch at the very least hasn't fallen from the top 5 when the checkered flag fell.

A top 5 for Busch on Sunday would push that top-5 streak to six and, more importantly, overcome a major gaffe he had at Kansas just last fall. It'd also mark his first top 5 at the 1.5-mile track.

Busch was just about to assume the lead of last October's event on Kansas' newly-repaved surface when he lost control exiting Turn 4. He made slight contact in the process, but the damage was enough to steal any good handling from his No. 18. A later crash sealed his fate for the day in 31st.

"Hopefully, we have a good car like that this time around and I don’t make a mistake like that," Busch said.

Busch, of course, wasn't the only driver to fall prey to a tricky Kansas track. The caution flag waved a track record 14 times in October — good for a series high among all tracks in 2012.

3. Martin Truex Jr. has had enough second fiddle
If you didn't sense his disappointment after Saturday night's race at Texas Motor Speedway, let's make one thing abundantly clear: Martin Truex Jr. is straight tired of finishing second. It happened again at Texas, and it happened twice last season at Kansas.

Truex was by far more dominant in the spring race last season before the re-pave, leading 173 laps. The Texas runner-up meant it has been 210 races since Truex won his only career Sprint Cup race at Dover in 2007 for Dale Earnhardt, Inc. If you'll remember, Truex's win that day came in a Monday race after a Sunday washout and was overshadowed by antics between Kurt Busch and Tony Stewart that left both wrecked and Busch parked by NASCAR.

See why Truex might be a bit tired of playing back-up?

"We had a good run in (Las) Vegas, and ran well at Texas," Truex said this week, more removed from his disappointing Saturday night. "It seems like our mile-and-a-half, big track program is pretty good and kind of like Kansas, so (I) look forward to going there."

4. Almirola returns to site of best career Sprint Cup run
Predictions for Aric Almirola to run well in the season's first 1.5-mile track race at Las Vegas Motor Speedway fell way short, but a very solid seventh-place finish last weekend at Texas should bode quite well for the No. 43.

Leading 69 laps in last fall's Cup return to Kansas, Almirola fell out of contention from the lead when he began suffering tire issues. Eventually, despite turning the race's second fastest laps and proving to be a top-5 car by speed both early and late in green flag runs, a tire exploded on Almirola and put him in the Turn 4 wall.

He finished 29th.

It was both a glimmer of hope and a knotting defeat for the underdog Richard Petty Motorsports team. Almirola, still searching for his first career win and just his third career top-5 finish, admittedly hasn't stopped thinking about a return.

"I've been looking forward to Kansas since last October when we left there. We were so good last fall. To have it all taken away with some blown tires really stung," Almirola said.

A solid run at Kansas would be extra nice for Almirola due to sponsor Farmland being headquartered nearby. He'll do battle in a brand new chassis built by RPM.

5. Kansas' own Clint Bowyer still searching for hometown checkers
Speaking of new cars, Clint Bowyer probably has one to sell you.

NASCAR's lone native Kansan celebrated the opening of his recently-acquired car dealership Thursday in his hometown of Emporia, Kan. In something befitting NASCAR's newest witty character, the dealership is one where both he and his brother formerly worked in decidedly lower-paying positions. It's also directly across the street from Emporia's Clint Bowyer Community Building.

Now, Bowyer will sell Toyotas from the Clint Bowyer Autoplex.

"There's a lot of renovation work and a lot of stuff to do, but getting the doors opened up for business was really neat and a big day for me," Bowyer said.

Bowyer is yet to own a Sprint Cup checkered flag from his hometown speedway, however. In 2007, he was extremely close — some would even say he won — when a late caution flag created controversy surrounding Greg Biffle's win in a shortened race. Since that runner-up finish, Bowyer has led just five laps in seven races and has two top-10 finishes at the speedway. He's also spent just 54 percent of his nine races at the 1.5-mile track in the top 15.

Those stats don't tell the whole story of Bowyer from a year ago, though, and extra numbers could show Bowyer as an unexpected but popular favorite for Sunday's race. Last October, Bowyer took sixth despite having the race's best average running position (5.858) and most laps in the top 15 (98.9 percent).

Will Bowyer finally hit big at Kansas? I guess we'll find out Sunday.

Plenty about Matt Kenseth (left) and Jeff Burton below. (ASP, Inc.)

Kansas Speedway was the site for one of the weirdest races of the year in 2012. On a newly paved surface with an unfamiliar tire compound, the race offered drama (Jimmie Johnson crashing), comedy (Danica Patrick attempting to wreck Landon Cassill, but wrecking herself instead) and action (Matt Kenseth stormed to the front late in the race – there is more on this below – to scoop up the surprise win).

Statistically, one race is really, really tough for information-gleaning purposes, but we can try. There are a few hot drivers leaving Texas, one under-the-radar performer last year at Kansas and a driver with a lot to lose, desperate for a sound Sunday run.

For PEER and other metrics with which you may be unfamiliar, I refer you to my glossary of terms on MotorsportsAnalytics.com.

56.29%  Kyle Busch is the most efficient passer in the NASCAR Sprint Cup Series with a 56.29 percent passing efficiency.

The winner in two of the last three Cup Series races is Busch, who also happens to be the most adept navigator through traffic in the new Gen-6 car. Ironically, Texas, the site of his most recent win, served as the only reliable race in which his pass efficiency was negative — 44.12 percent — but he started on the pole and averaged a 1.58-place running position en route to a fairly easy victory. Two of his three best single-race efficiencies, 56.25 percent at Fontana and 55.91 percent at Las Vegas this season came large intermediate tracks on which high horsepower matters, not totally unlike Kansas.

42.5%  Martin Truex Jr. led his first laps of 2013 at Texas, pacing the field for 42.5 percent of the race (142 laps).

He didn’t get the victory, but it was a strong showing for Truex, who has had a forgettable season thus far, finishing 24th or worse in three out of seven races. He heads to Kansas Speedway this weekend with two consecutive runner-up finishes, coming on both old and new pavement iterations of the track. There’s a caveat to that, though…

10.09  He finished second, but Truex only averaged a 10.09-place running position in last fall’s race at Kansas.

Truex is going to receive a lot of attention this week as a win favorite and a fantasy pick, but is the hype to be believed? He wasn’t nearly as polished on the freshly paved Kansas surface as he was on the old track. That 10.09 was the sixth-highest average running spot in a race that was caution-filled and as jumbled as your run-of-the-mill restrictor plate race. He might very well be a contender for the win on Sunday, but he isn’t nearly the lock as many will suggest.

128  Last fall’s Kansas race winner, Matt Kenseth, didn’t take the lead until lap 128. He led 78 laps on way to earning his only non-restrictor plate win of 2012.

I don’t think anyone expected Kansas to be a 1.5-mile version of Darlington. There were 14 cautions for 66 laps, meaning 24.7 percent of the race was run under caution. Patience was key and Kenseth’s approach to the race proved brilliant. None of the drivers that led in the first 100 laps of that race finished in the top 15. It’s not a guarantee that this kind of craziness will repeat itself, but understand that early leaders clearly aren’t impervious to adversity on this fast, frantic track.
 

Jimmie Johnson led 44 laps until this happened. (ASP, Inc.)

44  In a race in which his crash was the highlight, Jimmie Johnson led 44 laps (16.5 percent) and looked like a potential race-win contender in last year’s fall race at Kansas.

Prior to the lap 137 accident, Johnson and the No. 48 Hendrick Motorsports team looked awfully fast — and in fact, they were; they ranked third in average green-flag speed for the race — which meant one of the smartest teams in the garage area was one of the earliest adopters to the new Kansas pavement. No surprise there, huh?

0.57  Jeff Burton has the second-worst crash frequency in the Cup Series, currently crashing 0.57 times per race.

That isn’t a good-look for the 45-year-old veteran, who has had an abysmal — and possibly, final — season in the No. 31 car for Richard Childress Racing, ranking 38th out of 38 drivers with a -0.143 Production in Equal Equipment Rating. He needs a decent Kansas finish in the worst of ways. Currently averaging a 24.3-place finish in races with new crew chief Luke Lambert atop the pit box, his early-season production can be aided with an above-average finish this weekend. He finished 28th in last fall’s race.

8.500  James Buescher earned a PEER of 8.500 across five soft intermediate track races in the NASCAR Camping World Truck Series last year.

Buescher is the reigning Kansas winner, which makes sense considering the driver’s statistical fondness for the 1.5-mile non-quad-oval facilities. He won four out of those five races, claiming two at Kentucky and one at Chicagoland, in addition to the score at Kansas. He’s been quiet through three races in 2013, averaging a 13.7-place finish, so Saturday’s companion race to the Cup Series could help right his defense of the 2012 series championship.

It seemed a formality that once Martin Truex Jr. had fended off a vicious challenge from Jimmie Johnson that Michael Waltrip Racing would score its first Sprint Cup Series win since 2010.

Truex had led 173 laps and seemed on virtual cruise control as the laps ticked away in the STP 400 from Kansas Speedway. He pulled away for chunks of laps at a time after green flag pit stops — 45, 81 and 43 consecutive laps led on successive occasions — separating himself from the runner-up competitor by whole seconds.

Then, with about 35 laps to go, something happened to Truex’s Toyota.

According to team co-owner Michael Waltrip, the sun came out and changed the track, loosening up the car. Truex, however, was unhappy with the last set of tires that he reckoned did not agree with his machine.

Whatever the reason, a charging Denny Hamlin caught Truex and got by shortly after the final round of green flag pit stops to score his second win of the season.

Hamlin’s race-winning pass came on lap 237 of 267, and despite a last-ditch banzai effort with three laps remaining by Truex to reclaim the lead, the aero advantage Hamlin enjoyed carried him to the win.

“I knew that the only advantage that I had is when his (Truex’s) car got so loose that last run, I was able to make up a lot of time on entry and a lot of time on exit (in and out of the corners) because he was really fighting his car,” Hamlin said. “So really, as the driver behind, you can manipulate his car and make it worse for him by getting up close to him — and that’s what I kind of did a few laps leading up to when we passed him, is that I tried to run as close up to him on entry as I could and as close on exit. It takes away rear grip, and to a car that was as loose as what his was, they have no choice really but to back off and not wreck their car.”

The win at the 1.5-mile intermediate oval was somewhat of a surprise, in that Hamlin’s best finish on a comparable track this season was 11th.

“We just need to make 10 race cars just like this one and we’ll be fine,” Hamlin said. “There’s always things, areas that you need to work in. We feel like we’ve identified those areas and we’ve gone to work on them.

“So right now I feel like we’re bringing better race cars to the racetrack than what we have, and it’s still going to take time.

As for Truex, he and crew chief Chad Johnston continue to knock on Victory Lane’s door. Six of his finishes have been eighth or better this season and he has yet to finish outside of the top 20. That performance — he has averaged a 4.8-place finish in the last five races — places him second in the Sprint Cup point standings.

“The NAPA team was phenomenal today,” Truex said. “Just not really sure what to think about that last set of tires. (The) car had been really good all day, (then we) put the last set on and I was wrecking loose for the first 20 laps of that last run and Denny was able to get by me and once he did the race was over.

“(The) car got better longer in the run and I was able to get back to him, but I’d get three, four car lengths from him and pick up the aero push.”

Johnson held on for third after pit strategy forced him to climb out of a late-race hole. Matt Kenseth and points-leader Greg Biffle rounded out the top 5.
