Sure, Peters has been a headache to deal with, on and off the field, as evidenced by his penalty issues (three unsportsmanlike fouls and two for unnecessary roughness in 2017) and reported run-ins with coaches, but he has been absolutely sensational as a pure cover man. Peters leads all players with 19 interceptions since 2015, and his passer rating allowed has remained at an astonishingly low level during that span. (Peters' passer ratings allowed from 2015-17, according to Pro Football Focus: 67.1, 65.6 and 66.0.) Not to mention, he has discouraged quarterbacks from throwing the ball in his direction, due to his remarkable ball-hawking skills on the perimeter (targets have dropped from 151 to 91 to 72 each year). Considering how hard it is to find true shutdown corners in this league, Peters' feats as a playmaker are going to be nearly impossible for the Chiefs to replace.
