Heat coach Erik Spoelstra wants to focus on defense heading into both training camp and the new season.
It also appears as though he's working his players hard right off the bat this fall.
"We did a lot of defensive drills," Shawn Marion said, "and then we did some more defensive drills, then we did some more defensive drills, then we did some more defensive drills."
"It wasn't easy," Michael Beasley added. "I'll tell you that much. I had nightmares last night. I didn't know what to expect. I need to go to sleep right now."
"Two hours and 15 minutes of straight defense," Spoelstra said of their first session. "They didn't get into any shots, any kind of offensive thing, except to get shots at the end."
