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

Heisman Trophy trends finally appear to be changing. Defensive players are getting invited to New York City with increased regularity as one player from that side of the ball has been a finalist in three of the last four seasons. The age stigma has fallen by the wayside as well with Tim Tebow and Johnny Manziel each winning the award in just their second seasons on campus.

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.

With spring practice underway for many college football teams, the countdown to the 2013 season has officially started. With preseason predictions right around the corner, it’s never too early to start thinking about which players might be the next breakout stars.

The 2013 NFL Draft, held April 25-27, won’t be any different. The nose tackle position is a rare commodity that is highly coveted by every NFL franchise.

Look for teams to go early on defensive tackles.

With two of its best teams ineligible for a bowl game, 2012 was mostly a year to forget for the Big Ten. Despite having nothing to play for, Ohio State ran the table and finished with a perfect 12-0 record.

Ohio State fans will forever wonder "what if" about their undefeated 2012 football team. Urban Meyer led the Buckeyes to an unbeaten 12-0 record in his first season in Columbus and Braxton Miller blossomed into a Heisman Trophy-contending quarterback.

The battle to win college football’s 2013 national championship is officially underway. Spring practice kicked off for a handful of teams in February and will begin for most of the remaining FBS teams in March. While it’s often difficult to glean much from spring practice, it’s a time of new beginning for a1l 125 teams.

We have ranked every college football program in the country, based on the attractiveness of the position from a coaching perspective.
