Why the Bills took him: In a division with Tom Brady and some big, play-making receivers, Bills general manager Buddy Nix wanted to upgrade coverage skills with the 6-foot defensive back. Some scouts projected Williams as a safety, but Nix said they would keep him at cornerback.
How it affects the roster: Right cornerback Drayton Florence and backup Ashton Youboty are free agents. Although Nix wouldn't rule out re-signing Florence, the odds don't look good. Terrence McGee, Leodis McKelvin and Reggie Corner (nickel) are back, which will put Williams in a competitive mix.
Scouts Inc. says: Inconsistent but talented and most weaknesses can be improved. High in backpedal. Can allow some separation out of breaks and recovery burst is just average. Can give receivers too much of a cushion. Too quick to open and turn on comeback routes. Not as physical in press coverage as in run support and doesn't always re-route receivers with powerful stab at the line of scrimmage. On the other hand, has fluid hips. Can open and run with receivers in press-bail coverage. Quick feet and changes directions well for size. Closes quickly when receivers catch the ball in front of him and can limit production after the catch.
