'"The Bills have a few under-25 starters in significant roles this season," wrote Scott Kacsmar. "Sammy Watkins is the team's leading receiver and a quality playmaker when he's healthy, though his presence here matters less for his team than most of these young players because the Bills did not pick up his fifth-year option. Cornerback Ronald Darby charted much better in 2015 than he did last year, but he's starter material. Kevon Seymour charted well in limited opportunities as a sixth-round pick last year and should compete for the nickel corner job, vacated by Nickell Robey-Coelman. Right guard John Miller is important to Buffalo's run-heavy offense, and he finished second at his position in snaps per blown block. Linebacker Preston Brown struggles to stop the run, but has a surprising knack for big plays and led the NFL with 31 defeats in 2016."'
