Greatness is defined in so many different ways. Statistical production, individual awards, team success, longevity, supporting cast, level of competition, raw talent and athletic ability all factor heavily in determining overall greatness. Sometimes, you simply know greatness when you see it.

So all factors were considered when trying to determine who the greatest running backs of the BCS era have been. Here are the Top 50 ball carriers since the BCS was implemented in 1998:

Eddie Lacy, Mike Gillislee and Zac Stacy are gone, but the SEC isn’t hurting for options at running back.

Georgia’s Todd Gurley and Alabama’s T.J. Yeldon are back after standout freshman seasons. And both players are due for a bigger workload in 2013.

Mississippi State’s LaDarius Perkins quietly rushed for over 1,000 yards last season, while Texas A&M’s Ben Malena is an underrated option in a deep stable of backs.

The first round of the NFL Draft monopolizes coverage in the media and fan’s minds alike. While the first 32 picks are important and generally feature the most elite talents, the best organizations in football are competitive year after year because of quality middle round work.

The SEC is one of college football’s top conferences for quarterback play in 2013.

Texas A&M’s Johnny Manziel clearly ranks as the No. 1 quarterback for this season, as the sophomore hopes to repeat as a Heisman Trophy winner, while leading the Aggies to a SEC West title. Alabama’s AJ McCarron ranks as the No. 2 quarterback, with Georgia’s Aaron Murray not too far behind.

Coaching is one of the driving forces in building a national championship team or program. No matter how much talent a program has, it can’t win a national title if the coaching is questionable.

Considering how important coaches are to teams or even making preseason predictions, Athlon is taking a look at how each conference stacks up with its head coach rankings for 2013.

Auburn fans can't forget about the 2012 season quick enough. The first 0-8 season in SEC play, as well as widespread off the field chaos, led to the eventual ouster of head coach Gene Chizik, who led the Tigers to a BCS title in the 2010 season. Enter Gus Malzahn, who was the offensive coordinator for that undefeated national championship team.

With spring practice underway across college football, most of interest will focus on quarterback battles or incoming freshmen that enrolled early to get a jumpstart on making an impact for 2013.

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. If the quarterback is the most important player on the field and the guy who protects the quarterback — the left tackle — is the second-most valuable position on the field, then the player who can neutralize both must be No. 3, right? The defensive end position varies from scheme to scheme, but the goal is the same: get pressure on the quarterback.

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. The evolution of the tight end position has been interesting to track over the last few seasons. Smaller, quicker players are being lined up in the slot while bigger, more physical options are getting time in the backfield. Even the Colts drafted two tight ends last year, one to catch passes and stretch the field and the other to block and be a red-zone target.
