Take the Redshirt off and than completely bench him a game or 2 and than try putting it back on. Go to Depth Chart and completely take him out of the rotation (which will effectively bench him). Let him sit a game to show him he's not going to play and retry the redshirt. This way you won't lose the WE points, but also not loose his eligibility of going on the Redshirt list again. If it doesn't work, reinstate him again, sit him 2 games, and than retry the redshirt. Eventually he'll get the idea that all he's gonna do this season is pick splinters out of his ***.
