Dumervil's absence means very little ... Phillips, Ayers and Malik have a combined 13.5 sacks through 6 games. Champ's absence hurts, in that he is Champ Bailey and he was playing at an All-Pro level last season.
It's Von's absence that really hurts. Not just his play, but mentally it hurt, preseason was already half over when they announced the suspension ... that was a real hit. The tendency would have to be a reliance on Manning to light it up for six weeks.
