I love Sam and why he takes the contact makes me love him even more. He's not going to out run you, he's probably not going to shake more than one guy, but rest assured at the end of the run he's going to try to run your ass over and push forward. But even Sam can't take that pounding for a year without getting banged up and nicked; he's always an Iowa St. hit on a 3 and 14 scramble away from having that shoulder take a shot.
I love Colt, but even he found out pretty quick what happens when you lower your shoulder inside. Stone's not built for that - he's not fast enough to out run a McCulloch or Ossai to the boundary, so he's going to get pushed inside. Once he gets in there, he's going to take his fair share of hits from corners, safety's, nickels, lb'ers, and most will be faster than him. Milroe can bounce it outside and beat a lb'er or corner to the boundary, he can take it inside and outrun or shake a lb'er.
So that leaves us with his mechanics, which I don't think are that great. Everything is from below the ear, 3 quarter motion, he has to load low because he lacks the arm strength. I'll take Milroe, who already throws over his ear and snaps the football.
I think Buechele was every bit the quarterback Stone is, and I think Buechele threw a better ball and had better mechanics than Stone at that age. Watch Buechele's senior tape versus Stone and you tell me who you'd rather have. In our system, it's not even close between Stone and Milroe.
