I think the disappointment is more the defense allowing one of the worst offenses in the league with a rookie QB march down the field all game with very little resistance.
An Eagles player said something so heinous, that a Commanders player pushed him forcefully enough in the face to knock his helmet off right in front of the ref, and the Eagles player still got the 15 yard penalty. What could he have possibly said?
Oh, I don’t think Chris Jones was faking at all. That isn’t his style.
Mahomes walks around limping and then runs for 20 yards all the time. Either he had the lowest pain threshold ever, or he embellishes his “injuries”.
Faking an injury could change a team’s game plan if they actually believe it. Could make it less likely to have things like a spy. Could lead to a more aggressive pass rush if you feel like he can’t move out of the pocket.
Could even effect a defender’s angle of pursuit if they’ve been told all week the player is hobbled.
But I think it is vanity. Mahomes wants to recreate Michael Jordan’s “flu game” so bad he pretends to be injured like 3 times per season.
