^^^ I just cannot see Houston taking Manziel at #1 overall, at least not with Teddy Bridgewater available. Especially with the almost-perfect performance he had in his final bowl game against Miami. Scouts are going to see his size and arm strength as being superior to Manziel, and when they look at the improvements he made each of his three years as a starter:
Completion %: 64.5% - 68.5% - 71.0%
TD/Int rate: 14/12 - 27/8 - 31/4
...and the fact that when he played tougher opponents like Florida, Miami and UCF, he put up excellent numbers, he really seems like an easy choice at #1, should Houston decide that it really wants a franchise QB.
I agree he isn't the #1 overall pick. His off the field behavior alone will raise enough red flags to prevent that. Top 10,....probably (although I am not a huge fan of his on the next level). #1 overall, nope.
