The Big 12 season is approaching, and there's no league in which the quarterback position is more important. Want success? Experience is a good place to start. How do the QBs rank in experience? Let's take a look.

1. Landry Jones, Oklahoma (37 starts): Jones is the league's elder statesman by a long, long ways. He took over as a redshirt freshman in 2009 when Sam Bradford injured his shoulder, and didn't miss any of his 27 starts in 2010 and 2011.

2. Geno Smith, West Virginia (26 starts): Smith has been the team's unquestioned starter for each of the past two seasons, and should be ready for a big 2012 after topping 4,000 yards in 2011.

3. Collin Klein, Kansas State (15 starts): Klein had two more starts at receiver earlier in his career, but we're not counting those. Klein was a gadget QB in 2010, but took over as the team's offensive workhorse in 2011, accounting for nearly 70 percent of the team's total offense.

4. Casey Pachall, TCU (13 starts): Pachall played well in his first year as a starter, but often relied on his three star running backs in the offense and didn't top 3,000 yards. He's ready for more responsibility if necessary this year.

5. Seth Doege, Texas Tech (13 starts): Doege earned one start all the way back in 2009, but ceded that spot by the end of the game. He did no such thing in a strong 2011 season, though Tech missed a bowl game and had a losing season (5-7) for the first time in almost two decades.

6. Dayne Crist, Kansas (10 starts): Crist's 10 starts all came at Notre Dame, but there doesn't look to be much challenge from any other QBs on the roster this season. Does he have the offensive weapons to be productive?

7. Nick Florence, Baylor (seven starts): Florence started seven games in 2009 when Robert Griffin III suffered a knee injury, and earned a half of playing time last season against Texas Tech that cost him his redshirt season.

8. Steele Jantz, Iowa State (seven starts): Jantz got off to a strong start, but never figured out his very serious turnover issues. That cost him his starting job in midseason, despite three fourth-quarter comebacks to begin the 2011 season 3-0.

9. David Ash, Texas (six starts): Ash was the fourth-string QB last summer, but when Garrett Gilbert and Connor Wood transferred, it was up to him and Case McCoy to carry the load. By season's end, Ash had established himself as the future at the position, at least immediately, but Texas' coaches haven't given him the official designation yet.

10. Jared Barnett, Iowa State (six starts): Barnett took over for Jantz in the middle of the season and engineered wins over Texas Tech, Kansas and a historic win over No. 2 Oklahoma State, but struggled with inconsistency late and opened up the competition to Jantz in a Pinstripe Bowl loss to Rutgers. There's no assurance for either to be the starter after the spring.

11. Case McCoy, Texas (five starts): McCoy's gutsiest performance came in a comeback win over Texas A&M, but his lack of arm strength limited what the Longhorns could do in 2011. McCoy's got all the heart you could ask for, but his physical attributes bring about plenty of questions about his ability to carry the team over the course of his career.

12. Wes Lunt, Oklahoma State (zero starts): Lunt shocked even his own offensive coordinator by beating out junior Clint Chelf and redshirt freshman J.W. Walsh in the spring to earn the starting job. He still has to validate that spot in the fall, but Lunt is in a class of his own at the bottom of the Big 12 when it comes to experience. He's a big, NFL-sized QB with a big arm, though. Can his mind catch up fast enough to help the Cowboys defend a Big 12 title?
