I think it would be absolutely preposterous for him to even consider baseball. It's not like he's Bo Jackson, Deion Sanders, etc. He is a decent baseball player, and nothing more. He would be a longshot to ever make the big leagues, and even if he did, would certainly never be an All-Star or anything of that caliber. He will, however, be drafted highly, and probably be a starter somewhere within a year or two, if he decides to go to the NFL. He is a much better football player than Logan Payne or Ernie Wheelwright, and those guys are both drawing NFL paychecks. Is he a better baseball player than, say, Glen Perkins? Not even close.
All of the above being said, if I were him, I wouldn't even consider signing unless I were drafted in the first five rounds. Considering that's probably not going to happen, I'd consider his future in football pretty secure.
