Word out of Las Vegas is that Mike Miller's deal with the Heat is not secure, and that teams are advising him to consider not joining the team.
Miller says the deal is not done and it now sounds like there's a chance he won't join the Heat. We still think they're the favorites for his services, but it's not yet a done deal, and Miller could end up elsewhere. If the Heat need to make a stronger offer, they could pull a qualifying offer to center Joel Anthony. Stay tuned.
