In the college game, kellen Moore is lightyears ahead of Brock osweiler. I wouldn't touch Moore with a ten foot pole when it comes to the NFL, and I think Osweiler has great potential. Best case scenario for kellen Moore is he is a shorter Chadwick Pennington IMO. I see a lot of interceptions for Moore because of his lack of arm strength. Also he can't push the ball down the field, especially not in buffalo.
Osweiler on the other hand is athletic, mobile, six foot 8, and has an absolute hose. His negative is a lack of experience. But his ceiling is very high. I'll take Osweiler over Kellen Moore all day everyday.
