OK....why would he??? I know it's crazy sometimes to try to figure out a young kid's mind. But.....
He knows everyone on the team here and knows the system. He is with a coach that (from all reports) players like. He is on a team that has a chance to win the division and play for the conference title. He doesn't have Collins and VV in front of him anymore. He thought about being done and then decided for whatever reason to come back this year and play for Nebraska.
So.....why would he make the move?
