The thing with DBs (which is alot like OL): we only notice them when they fail to get the job done. On every other play (when they ARE doing their job), they go un-noticed (and unappreciated). A good portion of our sacks this year have been coverage sacks. So XR must be (most of the time) doing something good. That being said... I don't think we need to break the bank to keep him. In fact, I'd be in favor of trading him (in the off-season, so as to not upset team chemistry) to clear up cap room and open the door for Hughes (and Hill).
