I am totally confused as to how you got "in Wade's defense, the NT isn't required to penetrate".
First, I never wrote " NT isn't required to penetrate". His responsibility is to penetrate the A-gap. Each of the front 5 has responsibility for a gap. But it is expected that he'll draw the double team in which case his responsibility is to stack the A-gap and not be moved out of position. If he draws the single block, Wade needs a player to collapse the pocket, but he is not to freelance. His responsibility is the A-gap and only the A-gap, unless there is a stunt or other play called. If he is to rush the passer, it should be through the blocker. He is not free to abandon the A-gap or go around the block. Often you'll see a defensive player use a move to disengage from the block and in the process goes around the block to one side or the other. I guess what it boils down to is a strong bull rush is what is required of a NT in Wade's defense.
I just re-read the analysis, twice, and fail to see any mention of your statement. Other than a generic "(the NT) penetrates the A-gap", mentioned several times, the only other statement I find on the play of the NT is: "(the NT) is plugging the A-gap and ideally drawing the guard on a double team to stop the interior pressure."
