Man, I don't know. I just know too many 'tacklers' try to make the big hit, instead of just making the tackle. You hit and wrap up. That, at the nfl level, shouldn't have to be taught. Just like catching the ball - you can catch, or you struggle to catch. If you struggle to make catches at the nfl level as a receiver, you don't belong. At that point, it can't be coached.
