Explain how a kid being considered cocky can drop a kid 3 rounds but kids ahead of him failed drug tests, assaulted women, and actually been involved in murder investigations? I agree that he's cocky, some people don't respond well to that, but Calhoun, Harris, Conklin, and Allen came to his defense during the draft. Darqueze and Fowler didn't have to tweet out the things they did in his defense. The team seemed to rally around him, remember him and TOC, Terry huddling together on the sideline in the OSU game? he was out but was a vocal as anyone on the bench. This is the guy who gave his BT title game MVP trophy to his linemen. Yes he's cocky and can rub someone the wrong way but I think that's a very small part of why he fell. If it was a major factor, that's crazy. I think lower completion percentage, Bama loss, etc had more to do with it. Skipping the Senior bowl irked some but I think it's obvious he wasn't 100% until MSU's pro day.
The NFL drafts guys like Jameis Wiston and Taylor Lewan, they might use personality as a tipping factor between two players but they go with the guys that will win them games, not popularity contests.
