Myles Garret of the Browns wasn’t trying to help Steelers QB Mason Rudolph put his helmet back on, he was going for the KO. I have never seen a player thump an opponent in the head with a helmet before. I’ve seen angry batters throw them at a pitcher after being plunked, but that was a football first. Garret is done for the season. And the Steelers and Browns meet again in two weeks.
