Locker is way faster, has a stronger arm and has better mechanics. But Tebow is just better at football.
I really think Locker would be the same thing he is now if he went to UF, but with greater talent around him he'd make fewer mistakes. He will get the Jay Cutler treatment leading up to the draft. "Didn't have the weapons around him, with the limited options available he made plays, had to carry his team, etc."
Not sure where I stand on Locker as a pro prospect, but I really don't see any Tebow similarities other than, well, you know, being running white QBs.
