Lack of pass rush concerning or not?

[*ochocincos*]

Someone not even in the list mentioned in the OP is Zachary Carter...because he doesn't even have half a sack.

I thought this dude would be good for about 2-4 sacks this year.
Coming out of college, he was a bit of a tweener, but I thought he was a good pass rusher from the inside.
If he was (is) able to bulk up some, I thought he'd ideally be a good 3T down the road.

Disappointed with Carter so far.
Also Sample and Ossai.
