Oklahoma Playing Dirty

Just a quick hit on the Florida-Oklahoma game. Oklahoma is playing dirty. There was a horse-collar tackle on a FL running back (#3) - no call and it took him out of the game. A wicked facemask on Demps (FL #2) as he neared the end zone - called but just a nasty facemask. There was the uncalled and obvious cheap shot on Harvin (FL #1) when the Oklahoma defender yanked his legs after the tackle.
