The thing that I think has become problematic is the result of the play and who got killed. matters more than the intent. Palmer gets his knee shredded in a playoff game, nobody cares (no offense Steeler fans lol). Brady gets hit on the knee, all of a sudden it is a huge deal deserving of a new rule. Sometimes crap freaking happens and it doesn't mean the intent of the defender was evil or anything like that. It is a grown man's game played by grown men, people are going to get hurt.
What kind of routes are being ran? I've never seen an offense so pathetic in the redzone than the Steelers under Bruce Arians.
