That could just as easily have been called defensive holding. Compared to the blatant pick by KC on the touchdown play that caused Belichick to throw his tablet...but it was called the other way around.
Oh, and there was blatant uncalled PI on the play with the admittedly phantom roughing the passer. So the wrong thing got called but the right result happened on that play.
