I know scores aren't officially released, but rumor has it that Chris Leak got an 8 on the Wonderlic.

Not arguing with you, but where do you get the duarbility issues? He has never gotten an extreme number of carries here splitting time with Antoine Smith this year and Leon Washington last year. I know he hasn't been a horse, but he has held up fine when he was the sole guy (when Smith seperated his shoulder). I like him in terms of athleticism and I believe he never lived up to potenial here at FSU due to a really crappy Oline. Also, he needs to hit the hole. Too many times this year (besides the Emerald Bowl) he waited too long and had the defense catch up to him for a loss in the backfield.
Overall, he never lived up to the 5 star rating here at FSU, but he has all the talent in the world. He would be an excelent change of pace back, but I have never seen any question to his durability. That being said, I love the guy (can tell by the homerism haha), excellent personality, and he's an overall good guy.
