Maybe it's just me, but I still think the Denver O-line and their chop blocking are dirtier than Roy and Harrison put together.
I don't really see either guy as dirty (I am talking about in comparison to someone like Conrad Dobler), though Harrison is closer to it than Roy is. Roy's only claim to this is a tackle that was legal for 80 years and then outlawed because he hurt a couple of people. I still find that stupid. Owens got hurt last year and he wasn't horse collared. Injuries happen in the game. The horse collar rule is an extreme over reaction.
Meanwhile chop blocking continues to be acceptable. Stupid.
