With nearly one-third of the NFL coaching jobs expected to be vacant by year’s end — including sweet gigs like the Philadelphia Eagles, San Diego Chargers and New Orleans Saints, as well as the revolving doors of the Cleveland Browns, Kansas City Chiefs, Arizona Cardinals and Jacksonville Jaguars — silly season is officially upon us.

A freshman claimed college football’s most prestigious award for the first time ever this season when Texas A&M quarterback Johnny Manziel won the Heisman Trophy. But Johnny Football is nowhere near the first frosh to make a splash on the national scene during his rookie season. These are the 10 freshmen — of both the true and redshirt variety — who made the biggest impact in college football history.

The BCS is wrapping up its 15th season of action and Athlon Sports is continuing its series of BCS rankings. We ranked the best performances of each BCS bowl game and we ranked the best teams of each BCS conference. Now, we break down the top offensive units of the BCS era (1998-present).

Statistics, awards, championships and NFL talent were all considered and evaluated in order to label the Top 10 offenses of the BCS era. Only teams from BCS conferences were considered and teams from 2012 were not eligible.

The merits of recruiting rankings are debated in every sports bar and around every water cooler in the nation. Athlon continues its look at how each All-Conference team ranked as high school recruits with the first-team All-Pac-12 team.

The 35-ring circus of bowl season is full of sideshows, freak shows, split stats and split personalities. And the biggest and best bowls have the most exciting high-wire acts, thanks to their award winners, NFL prospects, high-priced coaches, rabid fan bases and big dog endorsement deals. Here’s a look at 15 weird and wild facts, stats and trends from the best bowls this postseason.

Each year a unique set of prospects enters the professional ranks with a chance to make an immediate impact on the country's most powerful sport. The 2013 NFL Draft, held April 25-27, won’t be any different.

Today, we rank college football's best defensive end prospects:

Johnny Manziel’s Heisman coronation capped a wild year of college football in 2012 filled with twists, turns and unexpected results.

Perhaps we should have known 2012 would be different from previous years when Alabama helped start things off with a familiar opponent (LSU) and a different result (a 21-0 rout on the arm of a quarterback ) in the BCS Championship Game.

As 2012 comes to a close, Athlon will count down the top individual performances in each major sport from the year, culminating with a full list of the top 50 performances of the year.

Technically, Johnny Manziel is a sophomore. So are Notre Dame’s Everett Golson and Oregon’s Marcus Mariota.

With the 2012 season officially in the books, it’s time to take an early look at college football’s top 25 teams for 2013. Alabama will be losing a few key players from its national championship team, but there’s plenty of talent returning to Tuscaloosa for the Crimson Tide to claim their third consecutive national title. While Alabama is a heavy favorite to repeat, determining the No. 2 team is a much tougher task.

College football’s 2012-2013 bowl season kicks off in Albuquerque on Dec. 15 and ends on Jan. 7 with the BCS National Championship in Miami. With 35 games, there’s a lot of college football to watch over the next few weeks. And needless to say, it can get a little overwhelming to take in every game with the holidays and plenty of unannounced visits from the in-laws. To help maximize your bowl watching experience in December and January, Athlon has ranked all of the bowl games in order from the must-see to the must-miss.
