First order of business would be to trade Deron, because he's going to LeBron anyway. Second order of business would be to get Jeff Hornacek onboard, and have he and Karl go to Greg's office and inform Greg that there will be no player revolts tolerated. None. If Greg can't back Horney and Mail on this, then it's a no-go. Assuming Greg says OK, fine, we take the squad as-is, and slowly figure out who the workers are. Reward the workers with the minutes, regardless of talent. Guys who don't work and don't get the team cohesion, don't play. Malcontents who begin yapping in the locker room? Waive them. Go to the D-League if necessary.
