"I'd say about two-and-a-half seasons I went inside and messed around," Matthews said. "I went inside in 2014, and we were blowing everyone out so I'd get to go back out on the edge second-and-long and third downs. They moved me back the next year, but (inside linebacker) Sam Barrington broke his ankle in the first game, and I ended up starting pretty much the rest of the year at inside 'backer at a moment's notice. The next year, I was doing my thing (at outside linebacker), and we were playing at Philadelphia (in late November) and they moved me back inside. I actually got lit up on a blindside block and completely separated my shoulder and missed some games ... and it wasn't until the playoffs till I got some strength back in it."
