“I like being left open,” Wallace said.
“Me and B.G. (Gordon) switched roles. “I had some good looks. When the guards get doubled-teamed or tripled-team we have to help them out any way we can. I was open and trying to take the pressure off Kirk and B.G. tonight.”
Hinrich scored 26 points in Sunday’s win over the Celtics and Gordon added 21.
Thomas, a rookie, led the Bulls in scoring for the first time.
“Our guards played well (Sunday), so Boston came out focused more on containing our guards,” he said.
