Re: Von Miller fined $15,750 for roughing Matt Schaub
The defender's goal should be to take the QB down as quickly as possible, while possibly hitting the ball with helmet or fist or stripping it. Lifting the QB (or whoever has the ball) before driving him to the ground is not only unnecessary, but also a move made for no other reason than to hurt your opponent. If players are allowed to do things simply to hurt their opponent, injuries are far more likely, especially when it's a D-lineman doing it to a QB.
I have stated already in another thread that I actually thought the Miller hit was worse, because it was so clearly intentional, or at least I thought. I get your point about Schaub possibly hopping a little to make a throw and then Von Miller hit him, making it not all his fault; but, I want to make the point that I am very much against defenders lifting the QB only to have more room to drive him to the ground, if that had been the case or not.
