Checking out SD's depth chart I see that they have Jamal Williams at nose tackle. Williams is listed as 6'2" 348 lbs. These are the types of guys Al Johnson typically has a lot of trouble with. Gurode seems like the better option this week but Parcells has already said Johnson is starting. Looks as if Rivera will be really busy between helping out Johnson as well as the big job of mentoring Pettiti during his first real deal. Seeing him in the J-ville game makes me feel a lot better about that situation.
