What exactly would a "break out" be for a 3-4 DE? 5, 6 sacks? That would basically put him among the leaders in the league at his position. 3-4 DE is not a big time sack position.
I think we should be happy with him being an absolute beast against the run and someone who can create opportunities for our legitimate pass rushers. If he does that, which I think he will, we should all be very pleased.
