Has nothing to do with it.
Teams have figured out their RPO game and now Mahomes has to make more reads and he has struggled a bit with it, along with the miracle throws not going his way.
Josh going up , pat going down
I bet that teams figured out their RPO game and now he doesn't have all those easy throws. You can hes frustrated and it has nothing to do with injury, hes still throwing the ball and moving like hes always has.
