Those first 7 games were not consistent though...you had three great games, three bad games and a decent game.
The INT rate was great...but the TD numbers were a byproduct of playcalling (pass/run ratio) and TD distribution...9/14 TDs were from the 5 yard line or in. Mack had 3 rushing TDs...one of which was a 63 yarder.
You could see the regression coming from a mile away...and it was already happening.
He is definitely elite athletically but I go back to the Clark comparison. Even the NFL had Clark as a 1st or 2nd round prospect because of his athleticism and he ended lasted until the 19th pick of the 3rd round. And I think Cleveland will suffer some of the same issues as Clark... athletic, lack of strength one advantage over Clark is Boise State runs a more NFL type offensive, so he is used to coming out of a 3 point stance and having to sustain blocks for a QB playing from under center.
