McKenzie's growth as a route runner has stood out during Buffalo's first four training camp practices while he sees extra reps in place of injured veteran wideout Jamison Crowder (undisclosed), Joe Buscaglia of The Athletic reports.

McKenzie saw limited opportunities as the Bills' fifth-leading receiver last year, hauling in 20 of 26 targets for 178 yards and one score over 15 regular-season games. However, his production included a breakout Week 16 game against the Patriots in which the 5-foot-8 wideout caught 11 passes for 125 yards and his lone touchdown of the campaign. With slot receiver Cole Beasley no longer on the team, McKenzie's head-turning performance thus far in training camp could catapult him ahead of Crowder, who is currently day-to-day with general soreness.
