I don't think he is too small. Sure he wont be carrying the ball 25 times a game, but what RB does now days?
Obviously his draft status is completely dependent on his 40. If he has a blazing fast 40 a la Chris Johnson, he will be a 1st pick.
Edit: And I don't think he compares to Sproles. LaMichael is bigger than Sproles
