But Young has been here 4 years and will have a degree in hand. I you are looking forward to your professional life (be it football, or something else), hanging around for an extra-semester to get 5 carries a game is a big ask. He has done his part by leading this team while he earned his degree, I can totally see him wanting to start the next phase.
On another note, I don't think we will ever know just how much value is brought to the team by unheralded leaders suh as Toren Young, Devonte Young, Amani Jones, and the Paulsonseses. Their contributions might not always show up on the field, but I think they mean a lot to the program.
