The biggest impact Von will bring is the attention he will be paid, creating opportunity for others...
Von getting 9 or 10 sacks isnt a big deal if teams dont double and triple him. I think teams will game plan for him until he shows they dont have to.
IMO, Von was the missing link on the defense, the reason they were willing to pay him so much. I really how he does not start slowing down in his first 3 years here.
