Patriots outside linebacker Adalius Thomas broke his forearm in yesterday's game against Buffalo. Perhaps this will open up some playing time for Pierre Woods and/or Shawn Crable. Crable hasn't dressed for a game yet this year, so I doubt he'll start in Thomas's place. But he could get some time on special teams or something.
The nutty Michigan coverage isn't so much about Harbaugh as it is a signal to the Big Ten that Fox wants to party.
