It's not supposed to be a job. It's supposed to be secondary to education. Admittedly, it's getting away from that, but I would like to hold on as long as possible.
I might be misunderstanding you, but if athletes fail at sports, they do not loose the education. Once a scholarship is given to a player, it is not allowed to be taken away for performance. If a player is kicked off the team (barring something like discipline issues), they still get the scholarship.
You can loose athletic scholarship for performance or injury. There are some exceptions where athlete gets to keep them for four years. But generally, coach has a lot of power to not renew scholarship the next year.
Only difference is that money don't go to athletes.
