Hold the Mayo for now. My impression from limited research is that he likely would have been a UDFA because of his lack of athleticism, so I can't make the leap quite yet.
He is a real solid MLB. He will be more of a stop gap guy in the league and may have a few seasons where he could start 16 games but he won't be THE guy at any point due to his lack of athleticism. After watching him at Texas State I did come away extremely impressed with his instincts and that's why he was drafted. He isn't a see ball, get ball player. He knows where the play is going before hand and acts on it.
