Buffalo Bills head coach Rex Ryan said the Bills will do their ‘due diligence’ on free-agent OG Evan Mathis, but he is ‘pretty happy’ with his guards.

Footballguys View: Mathis is getting quite a bit of interest on the open market. It’s wise for the Bills to look into the possibility of adding him. Mathis is going to come with a decent-sized price tag as he’s considered one of the best guards in the game.
