Coach Tom Thibodeau said he may play his starters more in tonight's exhibition finale against the Indiana Pacers at the United Center.
He also wants to see fewer turnovers, better concentration to start the game and improved defensive rebounding.
"Fundamentally, we have to be better," he said. "We had a lot of one-handed passes, one-handed catches. Some of the rebounding we were doing was one handed and that tends to happen when you're fatigued. We've got to get past that."
His players, meanwhile, were glad to take the home floor after Monday's first official practice at the United Center this season.
The Bulls haven't played at the UC since being eliminated by the Heat in Game 5 of the Eastern Conference Finals last year.
"This is the best part of Chicago for me, being able to play in this building," center Joakim Noah said. "It's exciting every time. You can be tired as hell --- there are going to be a lot of games in a row --- but for some reason, you're numb to all that when you play in this building."
