In an attempt to breathe life back into the Bulls for Saturday night's game against Phoenix, coach Scott Skiles will shake up his starting lineup, he said Friday.

Skiles did not reveal the changes but said they could be drastic.

Considering the Bulls have a young starting corps--the average age of the current starters is 23.2--there aren't many changes that could be viewed as radical. The most major would be pulling guard Kirk Hinrich.

Hinrich has been a steadying force for the Bulls since his rookie season out of Kansas in 2003-04. He started all but 10 games he played his first year, all 77 games in which he appeared last season and 27 this season.

Like many of his teammates, though, Hinrich is slumping. In their current five-game losing streak, Hinrich is last among Bulls starters in field-goal percentage (.350) and points per game (8.4). He was not available for comment after practice Friday.

After the Bulls lost to Charlotte on Wednesday night, Skiles told his players their ensuing practices would determine the starting lineup.

"Coach said, `We've been too married to the guys we have out there,'" Ben Gordon said. "`Nobody's spot is solidified. Everybody's spot is in jeopardy.'"
