Matt Stafford, Mark Sanchez and Josh Freeman are considered the top three quarterback prospects – in that order – at this early stage of draft evaluation.

Stafford, from Georgia, has decided not to throw during Sunday's NFL combine workouts. (He won't lift either, but he will run the 40-yard dash and do other testing.) USC's Sanchez and Kansas State's Freeman confirmed Friday they will go through full workouts in Indianapolis.

“It would kill me not to throw,” Sanchez said. “Too fun.”

Sanchez said Stafford's decision not to throw – he'll wait instead until his March 19 pro-day workout – had no bearing on his choice otherwise. Still, his competitive spirit is a good thing(albeit not a pick-deciding one) in the minds of those evaluating quarterbacks.

“It's sort of like running,” Lions coach Jim Schwartz said. “The guys that have confidence in their ability to run will run, so you want to see guys that have that confidence to go out. I know a lot of quarterbacks typically haven't thrown simply because they want to throw to familiar receivers, but yeah that does speak a little bit to a coach. A guy that has confidence to go out and throw at 7 in the morning or throw at midnight, 'Whatever you want Coach, I'll do it,' it probably does mean a little bit.”
