Particularly tested has been second-year Michael Beasley, who has been matched up with several outside-shooting big men.

"Michael actually is recognizing the situation quicker," Spoelstra said. "He's defending it better. So he's making progress."

Beasley said it's still an adjustment.

"I wouldn't say it's tough; it's just new," Beasley said. "The teams we played early on in the season, the first seven, eight games, weren't doing it. I wasn't really used to it.

"It's tough. It is. It really is. It's hard. We're playing in a new day and age; 7-footers don't stand around the rim anymore."

--Erik Spoelstra said he is impressed by the work of former Heat point guard Jason Williams in filling in for injured Magic starter Jameer Nelson.

"They get guys that fit that system, and Jason has always been a very clever and efficient pick-and-roll player," Spoelstra said. "Now he's getting the ideal situation for a pick-and-roll player. You get a dominant big man, who can roll and catch and finish, and every single other player has 3-point range with a green light. As we know, Jason's a dynamic passer and he fits perfectly in their system."

Spoelstra said he is not surprised Williams is leading the NBA in assist-to-turnover ratio.

"The thing that always goes unnoticed with Jason's game is he's efficient, doesn't turn the ball over. He makes the right play. He's unselfish. He makes other guys better and he doesn't make mistakes," Spoelstra said.

Williams scored 25 against the Heat on Wednesday night.
