How many times do we hear about a team that isn't tackling well? More often than not, I see players flying at players without wrapping up, leading with the head, going for the knees to cut a guy down. And it isn't always when that's the only way to make a play, either. Players are being rewarded for laying out players in any way they can. Often, that means the helmet goes right at a guy's head, or right at his knees. If you want to cut down injuries in football, then IMO the best way to do that is to reward solid tackling technique and penalizing leading with the head and blatantly going for the knees. Football will still be plenty violent. We're talking about people not being able to remember the room they were just in, increased alzheimer's, even early death.
