The hair pull was a bush league move. Then again, Hardy Nickerson got caught spitting on a guy. Follett head butted a guy whose helmet had come off. Those are two good guys that for whatever reason did something stupid on the field.
It was a foul. It was a bush league foul. Rip him for it if you want to. It's not worthy of dredging up issues he had a million years ago that have nothing to do with the situation.
