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 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.

The SEC West is arguably college football’s toughest division. With Alabama expected to be ranked No.

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.

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.

Coming off a seven-win season and a top-five recruiting class, Ole Miss heads into spring practice with momentum on its side. The Rebels return 15 starters, including quarterback Bo Wallace, linebacker Denzel Nkemdiche and receiver Donte Moncrief.

Thanks to seven consecutive national championships, the rest of college football is looking up at the SEC. And while there are some worthy challengers ready to make a push in 2013, there appears to be no end in sight to the SEC’s recent string of dominance.

We have ranked every college football program in the country, based on the attractiveness of the position from a coaching perspective. We considered many factors — tradition, facilities, location, money  — but in the end, we simply asked ourselves the following question: Where would we want to coach? Today we focus on the SEC.
