Video: Clay Matthews incorporates MMA

Green Bay Packers linebacker Clay Matthews discussed a number of issues in this interview with ESPN's Colleen Dominguez, most interestingly his mixed martial arts training this offseason.

"It brings a new level of violence and intensity that people don’t see," Matthews said. He added that "it takes someone who [is] a little off in the head. I’ll be the first to admit that."

I'm sure that's exactly what fans of the rest of the NFC North want to hear.
