Depending on what the kids did, Clayes should just cut them all from the team to send a message. The player need to fear the consequence of losing the privilege of playing on the team due to of bad behavior. Kill did it one way that Clayes obviously isn't good at, so you have to find a different way.
Obviously we should wait to hear all the facts, but if this is related to the restraining order again, those players should be kicked off the team. Even if you didn't do anything, you don't go and continue to antagonize or harass someone who just dropped a restraining order against you.
Hoping Winfield and Green are just academic issues (i.e. professors saying there is no way they can pass a class, or they are on the cusp of failing), they really looked to have great futures ahead of them.
