If I was a team I would look at Michael Vick and see the same thing in Mariota. I would be afraid of Mariota's durability in the NFL. Someone that plays at 210lbs will get destroyed by an NFL LBer.
that is a bad comparison. Mariota is 6'4 which means his body can pack on extra weight and he has better decision making/arm then Vick coming out of college. if you can, please watch the game from saturday vs Washington and you will see why some think he may pass TeddyB and be the 1st QB taken.
here is his cutups from draftbreakdown.com which is a great site.
