Mahomes has a win percentage of 77% in the NFL right now. With this ref he has a 75% win percentage. So… not much difference. Also on Mahomes, he may be 8-2 in those games but in 6 of the 10 games the Chiefs had more penalty yards than the opposing team.
As for the Bills, they are 9th most penalized team in the NFL this year. Last year they were the 13th most penalized teams. Bills are 1-3 with him reffing since 2018 with Allen but 2 of those times the Bills had less penalty yards than the opposing team.1 of the times the Bills had more but only by 15 yards and the Bills penalty yards that game were right on average. The only game that sticks out was this years game against Philly where the Bills had 11 penalties for 80 yards. Philly had 4 for 30.
So yeah, count me in the not buying into the ref conspiracy on this matchup.
