Don't look now but the defending champions are struggling. And by their standards, struggling big time.

The Miami Heat lost to the Houston Rockets last Tuesday and the San Antonio Spurs last Thursday. When they visited the rival Chicago Bulls on Sunday, they wanted to snap the skid to avoid duplicating their longest losing streak of the season they suffered last January when they lost consecutively to the Toronto Raptors, Washington Wizards and Brooklyn Nets.

The Bulls won in overtime, 95-88.

Joakim Noah had another spectacular all-around game-- both on offense and defense and outdid LeBron James, who again struggled shooting the ball.
