BIOGRAPHY: Former Arizona State quarterback who totaled 63.1%/2422/14/10 in nine starts last season. Suffered an injury to his left shoulder late last season and missed the final three games. Started the first seven games of the 2005 season at Arizona State before tearing ligaments in his right thumb. Finished the year with 2165 passing yards and 20 touchdowns.

POSITIVES: Patient, sells ball fakes, and buys time for receivers. Consistently looks downfield for the open wideout. Stands in the pocket and takes the hit in order to get the throw off. Quickly releases the ball. Puts touch on throws when necessary and leads receivers on screen passes.

NEGATIVES: Telegraphs his passes and does not do a good job of reading the defense. Short-arms his motion, off the mark with throws, and poorly places passes. Late on timing throws.

ANALYSIS: Keller has the physical dimensions to be a pocket-passer at the next level, yet he has shown minimal improvement to his game. He has been hampered by poor decision-making and injuries throughout his college career, which will make it tough for him to find a spot at the next level.

PROJECTION: Undrafted Free Agent
