Osweiler's height is his most noticeable trait. He's not just tall. He's gigantic. And he was easily the tallest quarterback in the nation in 2011.
During college, Brock was listed at 6'8", 240 pounds and most opponents thought he would have trouble getting out of his own way. But to their surprise, Osweiler has above-average athleticism for his size. He also has very good arm strength, but his critics say he's "raw" from a skills standpoint and can use another year in college.
Osweiler started just 15 games for Arizona State and only won eight of them, but the talent around him was not very stellar. It's also true that he was rarely asked to complete two or more progressions to find an open receiver.
Inexperience like that is common for quarterbacks that come from spread offenses, but it is not always insurmountable, as Carolina's Cam Newton proved last year.
If you're tall, have a cannon arm and can run, your chances for success can be good in today's NFL.
