Bill Belichick has no problem shuffling his defensive line. With the season-ending injury to DE Ty Warren, the unit suddenly looked vulnerable. Then in Week Four after giving up 134 rushing yards to the Bills, Belichick moved veteran NT Vince Wilfork to the end, and he has been there ever since. With Wilfork on the end occupying offensive tackles, Gerard Warren and Mike Wright have split time at the nose in the Pats' base package, with rookie Brandon Deaderick, Myron Pryor and Ron Brace swapping time along the line. "The great thing about our defense is the versatility that we have," Wright told PFW. In the next weeks with Wilfork on the end, the Pats allowed 92, 99 and 38 net rushing yards respectively, holding the Chargers to two yards per carry. One daily team observer remarked that the new alignment allows Wilfork to stop off-tackle plays and that Wright is quick and disruptive from the nose.
