Yes. You can kick them out of the locker room, but we still have to honor the scholarship as long as they're in Lincoln going to class...so that doesn't free up the scholarship for recruiting.
What another poster is proposing is what the SEC does--you make the player's life a living hell and force them to quit the team, thus freeing up the scholarship. It's how 'Bama has cheated their way to their NCs--every four years, by this practice, they get a full extra recruiting class worth of kids, and it's detrimental to the long-term health of collegiate football.
But some of our "fans" apparently want to win by any means necessary and feel that the end justifies the means, which is myopic and sad.
