Whether it is Belichick, Patricia, or Patrick Graham, somebody is doing something right. Most teams that have injuries to a few of their starters suffer dramatically (e.g., defense of the Dallas Cowboys or Chicago Bears; offense of the Tampa Bay Bucs).
We don't know who had the most input, but defensive line coach Graham in theory is working the closest with the free agents that were thrust into starting roles due to the injuries to Vince Wilfork and Tommy Kelly.
If we are going to give credit to Patricia and Belichick for making lemonade out of lemons on defense (and similarly to Dante Scarnecchia for dealing with injuries on the OL), then Graham deserves a bit of praise as well.
