Apologies if i missed this topic in another thread (moderators feel free to merge in). But I was astonished in last weeks game with Pittsburgh to see the Pittsburgh player (other Smith?) come up behind Brady and butt him helmut to helmut from behind. Why didn't that get an unsportsmanlike penalty immediately ? And even if for some reason that I can't imagine an official wasn't watching when a Patriot - and especially Brady - is walking thru Pittsburgh players, WHY WASN'T THERE A LEAGUE REVIEW AND FINE ?? ?? There is no such thing as: "Well, if a helmut to helmut hit is not too bad or if it's long enough after the last play, we'll just let it go". Hogwash. Some may recall my rather definite kudos for NFL refereeing in past posts, but this year has me shaking my head - including my former total respect for Mike Pereira, head of officiating.
