Garbage calls imo. If guys weigh 300 + lbs and they fall on you, so be it. That’s what they weigh, so tell the OL to block better. There was already a rule against body slamming a player ( which didn’t happen in these instances ) so any change was unnecessary. We saw the maddening inconsistency on full display Sunday with forward progress / in the grasp calls involving Allen and Rivers. The NFL needs to stop this nonsense. Players get hurt, including QBs. It’s the nature of the game.
