3. Kyle Fuller
Although we can't envision the Bears allowing Fuller to leave, he deserves mention for his marvelous 2017 rebound on the heels of a lost 2016 campaign that landed him in Chicago's doghouse.
Fuller tallied 22 passes defensed, trailing only NFC North rival Darius Slay among all NFL corners, in addition to two interceptions and a career-high 69 tackles last season. Just as importantly, he proved to be coachable, shining under the tutelage of Ed Donatell and Vic Fangio, who publicly questioned Fuller's buy-in and mental toughness after the former first-rounder missed all his third season following an August knee scope.
Fuller cut down on penalties and learned to play the ball in the air, the issues that plagued him most in a disappointing sophomore 2015 campaign, and played both the run and pass with a level of urgency unmatched by most NFL corners.
The question, then, is can the Bears feel confident that Fuller's transformation wasn't a contract-year aberration? It's why the franchise tag remains the most likely avenue for the two sides as they work toward a long-term deal that makes sense for everyone.
