MIAMI — The Miami Heat have little time to sulk.

A day after blowing a 21-point second-half lead in what became an overtime loss to the Utah Jazz, the Heat were back at work Wednesday. On Thursday, a rematch of the season-opener against the Boston Celtics awaits.

Starting with a 5-3 record isn't what the Heat envisioned. And considering the Celtics have already beaten the Heat once this season, the season's first official rough patch has arrived in Miami.

The Heat gave up a career-high 46 points to Paul Millsap in Tuesday's 116-114 loss. Miami was up 98-90 with a half-minute left in regulation, and still couldn't close out the Jazz.

Heat forward LeBron James says, "We still have a long way to go."
