Things aren't going so hot for the Miami Heat right now, but the mere sight of the Warriors at Oracle Arena on Wednesday night figures to spike the NBA champions' collective temperature. The Heat has lost three of four on its current six-game trip, which should be enough to fire up LeBron James and Co. They blew a 12-point lead in a loss at Portland on Thursday, then were whipped soundly by Utah on Monday in a game in which Chris Bosh had one rebound in 26 minutes and Dwyane Wade sat out the entire fourth quarter in a stew. Miami is tired, out of sync and cranky as it hits the Bay Area, and the Heat has gone under cover to boot. A scheduled practice at USF was canceled Tuesday, as was media access to the team. But even with Miami mum, everyone knows the score. The Heat has some heavy payback on the books due Golden State, and that might be just the tonic for the struggling champs. The Warriors beat the Heat 97-95 in Miami last month when rookie forward Draymond Green took a feed under the basket from Jarrett Jack and scored the game-winning bucket with 0.9 seconds left. They also beat the Heat in overtime at Oracle a year ago.
