I guess i am of the rare few that thinks Roy's technique is to hurt players. Calico's injury was so avoidable, Roy could have easily pushed him out of bounce. Not to offend anyone, but some of you guys live in LaLa land.
I don't disagree with you... I think there is a certain intimidation factor that Roy deploys.... but that is part of his role as a safety. His job is not just to tackle, but to intimidate like all of the great safeties that have come before him. So no, he does not just try to tackle people, he tries to knock the snot out of them or demoralize them while he tackles them. It's a mental edge in the game, what is going to intimidate you more, some guy pushing you forward and falling down for 3 yards or some guy grabbing you and dragging you down backwards for 1 yard. Believe me, the next time that same player comes to tackle you, you are going to be a little more hesitant. I'm not saying this is right, but it is the precedent for a player of his position. Football is a violent sport, it's not a pickup game with a bunch of friends.
