- He might believe that with a really good year he might have a chance to get into the pro's, but not believe that is possible at ND
- because he might not get enough PT even if he is the starter since there are so many TE's at ND, and
- because he might think ND's offense is trending more run heavy and not showcase his talents enough
- because he doesn't think ND's QB's will be good enough to allow him to have the year he would need.
- He might want to leave just to be a more focal point of an offense even if he doesn't see playing in the league as a likely option
- He might have some kind of beef with the coaches
- He might want a graduate degree that ND doesn't offer
- He might want to have a year in college where there are pretty girls and it isn't cold as fuck for half the year.
