The NFL Scouting Combine (Feb. 20-26) is just one step in the job interview process leading up to the NFL Draft (April 25-27). But the “Underwear Olympics” is a big deal. Millions of dollars are on the line during the 40-yard dash, bench press, vertical leap, broad jump, cone drills, Wonderlic and BOD Pod tests.

Here’s a look at 10 workout warriors who aced their tests at the Combine.

The Harbaugh Brothers are hogging — or Har-gging or whatever — all the attention at Super Bowl XLVII. But little Johnny and Jimbo aren’t the only tikes in the backyard turned titans in the world of sports. Here’s a rundown of the top 30 sets of active athlete siblings, with the combined accomplishments of the top 10 brothers, sisters and twins.

The top two teams in the NFC meet on Sunday to determine who will represent the conference in Super Bowl XLVII, as the San Francisco 49ers and Atlanta Falcons face off in the NFC Championship game at 3 p.m. ET on FOX. The 49ers find themselves in the conference title game for the second year in a row, but this time must get the job done on the road against the Falcons, who have lost just one game in the Georgia Dome this season.

The Green Bay Packers and San Francisco 49ers will get together for the second time this season when Saturday’s NFC Divisional playoff game kicks off at 8 p.m. ET on FOX. The champions of the NFC North and West divisions opened the season against each other, but the stakes aren’t the only things that have changed for this matchup.

The NFC West could be decided when the San Francisco 49ers take on the Seattle Seahawks at 8:20 p.m ET tonight on NBC. A win would clinch a second straight division title for the 49ers (10-3-1), while handing the Seahawks (9-5) their first home loss of the season. The Seahawks are currently seeded fifth in the NFC playoff bracket, but four teams are right behind them at 8-6, so they still have work to do to secure their postseason berth.

The San Francisco 49ers and New England Patriots face off tonight at 8:20 p.m. ET on NBC in what could potentially be a preview of Super Bowl XLVII. The 49ers (9-3-1) are trying to hold Seattle off for the top spot in the NFC West, while the Patriots (10-3) could potentially knock Houston from the top of the standings in the AFC. This also is a matchup of one of the league’s top defenses in San Francisco trying to slow down a New England offense that’s been lighting up the scoreboard most of the season.

The San Francisco 49ers dominating defense and methodical offense won for the second straight week, beating the Detroit Lions by the score of 27-19 in Candlestick Park. Jim Harbaugh’s club is looking like the early NFC favorite after defeating fellow NFC playoff clubs, the Packers and Lions, in their two victories.

Some of the national attention will be on the two coaches when the San Francisco 49ers host the Detroit Lions Sunday night at 8:20pm EST on NBC, but the real story is a solid NFC matchup between two postseason teams with high goals for this season.

The marquee matchup of the NFL’s opening weekend will take place at historic Lambeau Field, with the Green Bay Packers hosting the San Francisco 49ers at 4:25pm EST on Fox. These two NFC stalwarts combined for 28 regular-season wins in 2011, and both clubs have Super Bowl expectations in 2012.
