"His leadership is something no one seems to talk about," Cavs coach Mike Brown said. "He's, obviously, a very good leader.

"His leadership is something we didn't know about. He's a great person and a great family guy."

The Cavs thought they were getting a player who could score points in bunches.

"He can knock down the three-pointer, create a shot for himself and his teammates and he can run the offense," Brown said. "Those things everybody knows."

The Cavs have discovered that Williams is also a willing defender.

"Watching tape of him in college and his first year in the league with the Utah Jazz, he's a capable defender," Brown said. "He showed that he was a better defender than he showed.

"In the last game (against Washington), he took a charge for us that was a factor in the outcome of the game."

CAVALIERS 93, HEAT 86: The law of averages is working against them.

It's only a matter of time before the Cavaliers lose at Quicken Loans Arena.

However, it didn't happen Sunday. The upstart Miami Heat came into "The Q" and put quite a scare into the Cavs. But the Cavs (26-4) ran their winning streak at home to 16 games to start the season.

For the second consecutive game, they had to rally late to keep their impressive streak alive.

They embarked on a staggering 18-2 run midway through the fourth quarter to turn a six-point deficit into an eight-point lead.

Included in that run were 12 unanswered points, capped by forward LeBron James' free throw with 2:55 to play for an 85-77.

The Heat were held without a field goal for 4:26 in the fourth quarter.

Heat guard Dwyane Wade, the league's leading scorer, fired in 29 points, including 14 in the third quarter.

Guard Delonte West was outstanding with 11 points, four steals, four rebounds and four assists.

Power forward Ben Wallace had a game-high 14 rebounds, including six on the offensive glass, and three blocks.

Forward/center Anderson Varejao had 12 points and 10 rebounds, his second consecutive double-double.

It all added up to their 16th win in a row at home, and sixth consecutive victory overall.

"You can tell the fans are into it," James said. "They don't want us to lose all season."
