With spring practice getting ready to start for all 125 college football teams, quarterback battles will now take center stage. For most national title contenders – Alabama, Oregon, Ohio State, Stanford, Georgia, Notre Dame and Clemson – quarterback isn’t a question mark. However, there are a handful of teams that could be a conference title contender that enter spring practice with uncertainty under center.

With spring practice kicking off across the nation, the race to win college football’s 2013 national title has officially started. Although it’s hard to learn everything about a team in spring practice, the next few months are a good opportunity to get a look at how some of the open position battles are shaping up, along with how some of the underclassmen have improved since the end of 2012.

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 Pac-12.

College football's 2013 National Signing Day is in the books and Athlon Sports kicks off its 2013 team recruiting rankings countdown with an in-depth look at the best classes in the nation. Jim Mora got his tenure at UCLA kick-started with a great season on the field, nearly winning a conference championship. He parlayed it into the Pac-12's No. 1-rated recruiting class, dethroning the USC Trojans from their typical perch.

The start of spring practice for all 125 FBS college football teams is officially right around the corner. Army kicked off its spring practice on Feb. 12, while Tulane begins one day later on Feb. 13. Texas is the first BCS team to open spring practice, starting on Feb. 21 and Pac-12 rivals California and Stanford both start on Feb. 25.

Most of the talk on college football’s national signing day centers around which true freshman can make the biggest impact for a program for that upcoming season. While true freshman often make big contributions, the impact junior college recruits can have on the BCS level shouldn't be overlooked.

Recruiting in college football is downright nasty. It is a cutthroat, cannibalistic big business that is microscopically analyzed by fans, administrators and media members alike. The Pac-12 has watched its league and programs grow substantially in the past few years. Commissioner Larry Scott, the Pac-12 Network, a new media rights contract, six new coaches in the last two seasons and a variety of major facilities upgrades give Pac-12 schools plenty to sell to recruits.

The first Wednesday in February for college football coaches is almost like Christmas morning. With national signing day in the books, each coach can officially talk about their recruiting class after months of hard work, which includes anywhere from 10-30 prospects. While no coach will admit they aren’t happy with their signing class, there are plenty of clear winners.

Recruiting is the lifeblood of college football. Without good players, winning championships is nearly impossible. But there is much debate as too just how much recruiting rankings matter.

National Signing Day 2013 has come and gone. Fans, coaches and players alike rode a yearlong roller-coaster to the first Wednesday in February and it all ended with over 3,000 new college football players.
