The Jazz lost 84-78 to the Chicago Bulls on Friday and have not won since beating Philadelphia 103-101 on Dec. 20.
Matt Harpring and Gordan Giricek each had 13 points for Utah, which came back from a 13-point third quarter deficit to tie the game with 6:18 left. However, Chicago used a 9-0 run to take the lead back for good.
“Our guys have not really been quite tenacious enough to hang on the ball and make a good decision,” coach Jerry Sloan said.
The Jazz have lost five double-digit losses during their streak, and have been outscored by and average of 10.3 points per game during that span.
They have been missing Andrei Kirilenko, who was averaging 14.8 points per game before injuring his knee. Utah has lost 16 of 19 games in his absence.
The Bucks beat the Toronto Raptors 107-105 in overtime on Friday for their second straight win since a three-game losing streak.
“We were missing free throws, and guys were losing track of guys, but we hung in there and that’s a good thing,” coach Terry Porter said.
Williams said that walking away with a win made the team’s struggles a little easier to swallow.
“We have to clean that up, but knowing we have to clean it up with a victory is better,” Williams said.
Center Dan Gadzuric started after missing Tuesday’s game with back spasms.
