When it comes to YAC, BUF’s offense is friendlier for RBs. Harris had a washed up Cam Newton and noodle arm Mac Jones to take the heat off the running game…teams played the run time and time again. Defenses have to defend Josh Allen, preventing them from doing the same against Buffalo.
Cook, in his rookie year, averaged 5.7 YPC, a full yard higher than Devin. Cook and Devin share a lot of qualities, Buffalo needed a physical presence at RB to pick up the tough yards. The less we have to rely on Allen to do that, the better.
