I don't think these are official new rules yet but I love them.
I don't know what it is but I can't stand seeing player's hair flying around behind them as they run around the field. To me the best play in the NFL since Elway did the helicopter was whenn Larry Johnson pulled Polumalu down by his hair. Anyway it looks like they are not going to allow hair to be exposed if it comes out of the helmet. I like it, great move!
The incidental face maske call will be removed, now you just get the 15 yarder if you actually tug on the helmet... I like this rule makes sense.
And the one that really bugged me was the force out rule. I had nothing but hate for the rule allowing the officials to judge a catch that came down out of bounds saying that "if the defender wouldn't have pushed him out, he would have came down in bounds". I always thought, "well IF the defender wasn't there he would have made a touchdown on every play". Fact is, the defender was there and did his job defending. Great rule!
Three good rules I think!
