"As a coach, I'll take it against a high school team," Washington coach Randy Wittman said.
Wittman, whose team was decimated by injuries early this season, pointed out that star point guard Derrick Rose has yet to play for the Bulls, and All-Star forward Luol Deng missed his fifth straight game with a strained right hamstring.
"I've been there, but a win's a win," Wittman said.
Wall, who started for the second straight night, has been the catalyst for the team's recent success.
"It's not just me, man. It's never just me. I wanted to come in and be a spark for the team," Wall said.
"I'm just doing a great job of getting easy shots for my teammates."
The Wizards outscored Chicago 23-11 in the third quarter to take a 73-55 lead. The 11 points were a season low for the Bulls. Chicago had twice as many turnovers (six) as field goals (three) in the period.
"I thought we played low energy tonight," Bulls coach Tom Thibodeau said.
"You gotta get ready for everybody. ... When you start taking shortcuts, the results aren't gonna be good."
