I'm going with Stephon Gilmore as the Bills breakout star. Kept getting better and better as the season wore on. He's physical, annoys the shit out of receivers, and can cover up mistakes with his athleticism. Needs to watch out with the clutching and grabbing, developed a bad rep and was getting flagged for clean plays. Has to cut down on looking into the backfield. He locked guys up with the most pedestrian defensive attack in the league, they never blitzed. With a scheme that's set to be more aggressive Gilmores poised to turn heads around the league this year.
Sleeper pick is Nickell Robey. UDFA rookie is undersized for the corner position but he's an extremely athletic guy. On a team with questionable corner depth, he's going to get an opportunity, especially with how many corners Pettine likes to put on the field. Will he overcome his size limitations, he weighs about as much as I do and I'm a bit taller than him. I can't picture myself playing corner in the NFL, but he looked the part in mini camps and certainly has the athleticism to cover. Intriguing player that may surprise a lot of people.
