Mayo was a tackling machine in college with abilities that should transfer well to special teams, though he didn't play special teams at Texas State the past three seasons. He may need to prove his worth there in his battle for a roster spot because others in the position group include offseason acquisition Jason Trusnik – who has 76 career special teams tackles – as well as 2014 special teams tackle leader Ben Jacobs. To boot, linebacker Kevin Reddick had a big fumble recovery on special teams in last year's NFC Wild Card playoff victory over the Arizona Cardinals.
