Carter is the best pass rusher this team has had in year. It isn't saying much, but that is a clear fact. It is clear that he is far better than TBC was last year hence why TBC was a backed up Jermaine Cunningham who doesn't even dress right now. Without Carter, this defense would be significantly worse right now. He was a very good pick up for Pats. As a Jets fan, you might not have realized this.
As for Reggie White, you have this stupid theory that if a DE doesn't play the 3-4 that he is not as good as a DE who can be a 3-4 OLB. Reggie White was probably the best 4-3 DE all time, but he would have probably sucked in a 3-4 because he was too big to play OLB and probably too small for DE.
