Video: Reiss' key matchup for Patriots

In the video above, ESPNBoston.com’s Mike Reiss gives his keys matchup for the Patriots against the Packers on Sunday night:

“With rookie cornerback Devin McCourty’s status uncertain with that rib injury, it could thrust second-year cornerback Darius Butler into a possible starting role. When you look at the strength of the Packers offense -- especially if quarterback Aaron Rodgers plays -- receivers Greg Jennings and Donald Driver, that’s a big matchup for Darius Butler."
