Rat's production has dwindled. He is tracking for zero sacks this year. I know sacks aren't everything, however, he is undersized and isn't in there for his run stuff capabilty. Add to that he has missed half the season due to various nagging injuries going back to training camp -- which is exactly what you might expect for a very undersized 3-4 NT -- all the double-teams over the years by 650 lbs of guard & center every play have taken a heavy toll. Of course, much of this was already apparent when Jerry, ever loyal, extended him with a excessive contract extension.
