With no clear No. 1 quarterback returning for 2013, the Big 12 has an intriguing blend of potential and uncertainty surrounding the most important position on the field.

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 head coach rankings for 2013.

With spring practice underway for most 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. 

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.

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.

Transfers are a big part of any college football season, and 2013 is no exception. There’s a handful of talented quarterbacks making the move to a new school, including Jake Heaps at Kansas, Tom Savage at Pittsburgh and Jameill Showers at UTEP.

The start of the 2013 college football season is still months away, but it’s never too early to start thinking about preseason predictions and some of the top games to watch in each conference.

Even though Oklahoma finished 10-3 and made an appearance in the Cotton Bowl last year, coach Bob Stoops wasn’t satisfied. As a result, the Sooners had a shakeup on the coaching staff, with three new faces coming aboard for 2013.

With no clear favorite entering spring practice, the Big 12 should be college football’s most intriguing conference to watch when preseason picks are released for 2013.

Each year a unique set of wide receiver 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. This group will feature freaks of nature who need to polish their game. It has lightning quick jitter-bugs who will dominate the open field from the slot position. And it has elite, big-framed, down-the-field vertical threats as well. Whatever offense your favorite team runs, there is a wide receiver in this draft for you.
