Remember, the Transfer Portal is actually the Washout Portal. Over half of all players in it never play in college again. Most guys who transfer, and actually play another year, are mostly destined for another year of scout team, followed by another trip to the Transfer Portal which will end their career.
College football is a game of routine mostly consisting of tedious practice, even more tedious exercise and worst of all meetings. There are very few days a player is actually playing in a game. Many guys are so accustomed to this routine they cannot see their lives without it. Moreover, they are under a lot of pressure to live the lives others want them to live. I would advise any Zip who doesn't want to play anymore, and only has walk-on offers, to evaluate whether or not they want to really attend college. If they do, stay at Akron, do whatever you have to do to pay tuition and graduate. Do something like the Army Reserves or ROTC because the physical fitness requirements can easily be achieved. It's a great school. There are tons of things to do other than play football. Reality can be difficult, but face it.
