Roy simply runs towards ballcarriers and pulls them down from behind. The fact that T.O., Tyrone Calico, and Musa Smith were injured because of Roy's tackling technique shouldn't be the impetus to initiate some silly new NFL rule prohibiting the maneuver, IMO.
Let's get real...Bronco O-Lineman have been chop blocking and injuring defensive players for years now and nothing has been done about it. Now that a Cowboy player is at the center of the discussion once again, there needs to be a new rule? Why am I not shocked!
Erik Williams and his hands initiated a rule change. Emmitt Smith and his helmet removal celebrations resulted in a new NFL rule. I can only speculate that if Ed Reed had made those same tackles, the media would be singing his praises.
Roy pulls ballcarriers down from behind on occasion. If players don't want to get tackled from behind, perhaps they should run a little faster.
