Keller spent his first three seasons of college at Arizona St. He took over the starting job as a junior in 2005, and had an amazing start to the season. In the first seven games, he threw for 2,165 yards and 20 TD�s to just nine interceptions until he went down with a hand injury. A QB battle in which Rudy Carpenter was named the starter caused Keller to transfer to Nebraska, where he sat out the 2006 season. His only season with the Huskers was cut short with a left shoulder injury but he still managed to throw for 2,422 yards, while completing over 63% of his passes for 14 touchdowns and ten interceptions.
Keller has all the skills to develop into a quality pocket passer. He has a very good arm, capable of making every throw on the field. He is not afraid to unleash the ball all over the field, and has the confidence in his ability to make big plays. Keller has good size and the frame to be able to take hits in the pocket and continue to get up. He still has some development and upside left in his game.
Inconsistency has been the big issue with Keller. He has made some questionable decisions at times, and may believe in his arm too much. He will try and force the ball into coverage to make a play instead of seeing the field and making the smart decision. He also has less that two seasons of starting experience at the college level, so he still needs more work.
Sam Keller is a quarterback that needs more time, but has the skills to develop. He needs more experience overall, especially in the aspect of reading a defense. If a team can have some patience and be willing to develop his skills, he is a player that could develop into a legitimate NFL quarterback.
