A closer look at QB experience in the Big 12

Last season, the Big 12 had just one starting quarterback (Oklahoma State's Wes Lunt) begin the year without a career start. It could look much, much different this time around. Experience at the position is always helpful, and here's a look at who's got how much across the Big 12 among players who could be Week 1 starters:

1. David Ash, Texas (18 starts): Ash has gotten better and better as his career has progressed and he threw almost twice as many passes in 2012 as a full-time starter as he did in 2011. The result: A jump from four to 19 touchdown passes and the same number of interceptions. He also completed 11 percent more of his passes (67 percent). But he also has to eliminate games like he had in 2012, when he completed 50 percent or less in three starts.

2. Casey Pachall, TCU (17 starts): Pachall was leading the nation in passing efficiency before an October drunk driving arrest led to him leave the program to seek treatment for drug and alcohol addiction. His decision-making on the field is his biggest asset. He has 36 career touchdown passes to just eight interceptions.

3. Jake Heaps, Kansas (16 starts): All 16 of Heaps' starts came at BYU, but he lost his job after some sophomore struggles in the wake of a breakout freshman season. He threw for almost 3,800 yards and completed 57 percent of his passes with 24 touchdowns and 17 interceptions in almost two seasons in Provo.

4. Trevone Boykin, TCU (nine starts): Boykin's got a ton of speed and a big arm and did better than most figured he would while filling in for Pachall last season. The rising sophomore completed just 57 percent of his passes but threw for at least 250 yards in four games.

5. Clint Chelf, Oklahoma State (five starts): Chelf's upside is minimal, but he proved himself more than competent after sticking out the first half of the season as OSU's No. 3 quarterback. A year after being beaten out by a true freshman in the spring, he's OSU's presumed starter. He completed 60 percent of his passes for 15 touchdowns and six interceptions after stepping in for an injured Wes Lunt against Kansas State.

6. Sam Richardson, Iowa State (three starts): Richardson was the third ISU quarterback to get a start last season and had a huge game in a blowout win over Kansas but completed less than 50 percent of his passes the rest of the season. It's his team for the time being, but I'm betting Paul Rhoads is prepared to hand the ball to Grant Rohach if Richardson strings together many more games like he had against West Virginia and Tulsa.

6. J.W. Walsh, Oklahoma State (three starts): Nearly knocked off Texas in his first start, but played well in blowout wins over Kansas and Iowa State. A leg injury cost him half of his season, but he's found a niche in the offense with a short yardage package and proved himself a capable starter.

8. Clint Trickett, West Virginia (two starts): Trickett appeared in 16 games at Florida State, nearly knocking off Oklahoma in 2011 in Tallahassee. He made just two starts at FSU, but threw for 336 yards in a close loss to Clemson in one of them.

9. Michael Brewer, Texas Tech (zero starts): Brewer got a little bit of playing time behind Seth Doege last season, completing 70 percent of his passes for four touchdowns and no interceptions. It'll get tougher as a full-time starter if he officially wins the job ahead of Davis Webb this fall.

9. Blake Bell, Oklahoma (zero starts): You know him as the BellDozer, and he has more career rushing touchdowns (24) than pass attempts (20). He left the spring as the Sooners' almost sure heir to Landry Jones.

9. Daniel Sams/Jake Waters, Kansas State (zero starts): Waters is a junior college transfer who hasn't played a snap of major college football. Sams rushed for 235 yards and three touchdowns in mostly mop-up duty last season, but after Collin Klein suffered a head injury against Oklahoma State, he completed 6 of 8 passes for 55 yards.

9. Bryce Petty, Baylor (zero starts): Petty's never played a meaningful snap with the Bears and has just 14 career pass attempts. He's been in the program forever and has the physical skills to be great, but his career is starting on a fresh slate in 2013.

9. Paul Millard/Ford Childress, West Virginia (zero starts): Millard has served as Geno Smith's backup in mop-up duty, and threw 34 passes in the past two seasons. Childress redshirted last season and hasn't seen any playing time.
