Tyrann Mathieu is not a really good corner. He was always at the right place at the right time and a hell of special teams guy as a returner. As a cb, not so great, but becuase he scooped up the block punts, fumbles and deflections, it made much better than he is. He use to always get burned on big plays.Forgot the guys name, whom the Cowboys drafted last year,he was the one covered the opponents top WR. I watch a lot of college ball, a lot more than pro. The guy is nothing but a super fast pot head
