On the office screen, there will be a link next to the kid's name to redshirt him. Click it. You'll receive an immediate e-mail from the assistant coach telling you that the paperwork went through. Within a few hours you'll get an e-mail from the kid either saying he's cool with it or expressing negative sentiments. If he's unhappy about it, check his work ethic...it will have dropped, how much depends on a case-by-case basis..if you're okay with the drop, do nothing (it won't go down further), if it went down too far (like to 1), then you can go back to the office screen and remove the redshirt and get the lost work ethic back. (you're also free to wait a cycle or two and try again...sometimes the kid will accept it later after initially rejecting it. Just remember if he gets into a game at all (regular season, not exhibition) he's unable to be redshirted that year.
