Hedo Turkoglu scored a career-high 39 points, but Howard had only three points and 14 rebounds.
"Our big guys really took the challenge to make it difficult for him," Jamison said. "Not to get him bouncing around and dunking and Supermanning and all that stuff. We really wanted to prevent as many points in the paint as possible."
Orlando had a chance on an inbounds pass with five seconds left, but Turkoglu's layup was short and officials didn't call a foul.
Howard sat much of the game in foul trouble and was frustrated by the Wizards' physical presence inside. The All-Star turned the ball over four times and shot 1-for-6, failing to score from the field until the fourth quarter.
He had 10 rebounds before halftime but picked up his fifth foul with about 9:30 left in the fourth.
Raptors 96, Heat 54 -- Andrea Bargnani and Anthony Parker each scored 14 points, and Toronto held visiting Miami to the third-lowest point total in the shot-clock era. The Heat was just five points off the NBA record low since the shot clock was introduced in the 1954-55 season - the Chicago Bulls' 49-point effort against the Heat in April 1999. The 42-point margin of victory was the Raptors' largest in franchise history.
76ers 115, Nuggets 113 -- Andre Miller scored 28 points, and Allen Iverson's return to Philadelphia was spoiled. Iverson, playing in Philly for the first time since he was traded Denver in December 2006, led all scorers with 32 points and added eight assists.
Cavaliers 89, Pistons 73 -- LeBron James scored 30 points, moving closer to becoming the Cavaliers' top career scorer, and host Cleveland defeated Detroit. James came in needing 35 points to pass Brad Daugherty as the Cavaliers' scoring leader.
Pacers 102, Bobcats 95 -- Flip Murray scored 22 points, and host Indiana beat Charlotte for its second straight win.
