Mahomes, in particular, was quick to hold his hands up and admit his actions were out of line and that he was trying to be a better role model.Mahomes continued to vent his frustrations with AllenX@JPAFootballReid was also fined for his comments made about officials after the Bills defeatGettyMahomes backtracked on his comments once he’d cooled downGettyDespite their momentary head loss, the future Hall of Fame pair managed to regain their cool for the rest of the season.The Chiefs went on to win the Super Bowl, avenging their regular season loss to the Bills along the way by marching into Highmark Stadium in the Divisional Round and coming away with a 27-24 victory.Josh Allen’s record vs Patrick MahomesBuffalo got their own back on Kansas City in Week 11 of last season by handing them their first defeat of the campaign.Allen put on his Superman cape and accounted for 317 of the Bills’ 366 offensive yards, including a brilliant 26-yard touchdown run with 2 minutes and 17 seconds remaining.It saw his personal record against Mahomes improve to 3-2 in the regular season, although his rival is 4-0 when they meet in the playoffs.Now, they will go head-to-head once again with the losing team suddenly looking over their shoulders in the race to secure a playoff spot.
