You're right of course. But how long do you think that would last? Once there had been a couple of games with penalties given then the players would have to stop and we would see a better game. Bit like diving, now players get booked for it there is less of it.
Of course it was a penalty. Not sure how anyone can claim otherwise. Dunk nearly had the shirt off the guys back. Keane may well have been holding Dunk's arm but the more obvious was the shirt pulling..
