You're pretty far down this rabbit hole I take it.
Far enough down it that you're sure about the details of the MB deal, and you're sure that his absence is responsible for the entirety of the 41 points the defense gave up.
He was touted throughout the year as a possible Belichick heir. This Sunday, you cannot say Matt Patricia burnished his resume. You can only say you have a hypothetical excuse for the performance of the defense.
On the other hand, you can say without doubt that the offense is continuing to play very well.
Understand we're talking about coordinators, and in BB's case, the coach. It won't do much good to say "yeah but the offense has Tom Brady." They can't very well judge coordinators independent of their performance on their side of the ball.
Props to Matt P. on his body of work, and good luck to him in Detroit. I'm not talking him down. Just letting you know, coordinators are going to be judged on their performance, not any excuses we come up with for them... and SBs are disproportionately weighed vs. regular season work.
