CLEVELAND - No Joe Johnson, no problem for the Atlanta Hawks.
Playing without their star guard and leading scorer, the Hawks never trailed and rolled to an 99-83 victory over the Cleveland Cavaliers on Sunday night.
Marvin Williams, taking advantage of increased playing time, more than made up for Johnson's absence with a season-high 31 points. Al Horford added 20.
"I got going early and my teammates kept coming to me," Williams said. "I had a big night and our team had a big night."
Johnson, who averages 18.5 points, sprained his right thumb Saturday, but the Hawks didn't need him to beat the Cavaliers, who have the worst record in the NBA.
Williams shot 9 of 14 from the field, including three 3-pointers, and 8 of 9 from the foul line in 43 minutes.
"Marv looked very confident out there," Horford said. "He really just took what the defense gave him and he was being aggressive and attacking the rim. I think when he plays at that level, not necessarily scoring (31 points), but just being aggressive like that, I think we really are a different team."
Johnson missed two weeks earlier in the season with an elbow injury, so Williams and his teammates are familiar with taking on added responsibility.
"It was something we had to learn to do," Williams said.
"The guy doesn't miss many games. We knew what we had to do. Everyone had to chip in a little more."
Coach Larry Drew isn't sure how long Johnson will be out. X-rays taken Saturday were negative, but Johnson didn't travel with the team to Cleveland.
Horford was 10 of 15 from the field and had 10 rebounds, while Josh Smith scored 13 points and had a season-high 18 rebounds.
The Hawks, who clinched a playoff spot in the Eastern Conference by beating New Jersey on Saturday, lost eight of 11 before winning the last two.
"I thought we really played well together," Drew. "I thought we really shared the basketball. We really did a good job moving the basketball."
For Cavaliers coach Byron Scott, the game was a repeat of the same bad movie he's been watching most of the season.
"We got off to a bad start," he said. "We didn't come out with the energy and aggressiveness we needed to come out with, for whatever reason."
Baron Davis, who is expected to move into Cleveland's starting lineup soon, came off the bench and scored 19 points. Ramon Sessions added 13 points for the Cavaliers, who have lost nine of 11.
Atlanta scored the first eight points and led by as many as 11 in the first quarter. Atlanta was ahead 52-39 at halftime and built the lead to 19 in the fourth quarter.
Kirk Hinrich scored 13 points while Jeff Teague added 10 for the Hawks, who shot 50 percent from the field.
