Would Aqib Talib been ejected after that face mask then?
They should limit it to actions that are both intentional, and blatant.
Let's face it, a lot of penalties (including those labeled 'personal fouls') are unintentional - they're just boneheaded mistakes.
But some penalties have malicious intent. And malicious consequences.
If you treat all the personal fouls the same, then you're going to have guys ejected for completely BS reasons, and go way way beyond the intended perception of trying to simply create a safer sport.
I received a head knock playing Aussie Rules, and I was KOd, but I wasn't wearing a helmet. That was over 30 years ago, and I still suffer from migraines because of it. It has been proven that helmets themselves don't prevent brain injuries. They only prevent superficial damage, not long term damage.
Any player penalised for a helmet related offence should be ejected from the game, and given a week's suspension, at the minimum.
You haven't joined any rooms.
