I gotta go with Jenkins and Brockers. I think both guys have a real shot at being among the best at their position. Jenkins didn't exactly thrive last year, but we've seen what he can do. Not even Quinn made a splash in Year 1 the way Jenkins did... the guy has star power. He just has that "it" factor.
Brockers will breakout in a big way also IMO. But as a DT, his results will be slightly less visible in general. He won't get the recognition of a Quinn or Jenkins.
Ogletree... hard to say. I can see him having a big year, but I can also see him needing another year before he really starts to shine. Hard to say.
On offense... I think Bradford and Tavon get the most attention. I think Tavon will just light it up. I don't care what anyone says about his rookie year... I think he had a special season and he really showed me something. He had those brief flashes of greatness that we typically see from rookies who go on to be big time players.
P.S. What the hell is my avatar?
