The Chicago Bulls lost on Friday to the Cavaliers and on Saturday to the Timberwolves as they adjust to playing without Derrick Rose.
‘‘The big thing for me right now is our improvement,’’ Thibodeau said. ‘‘That’s what I want our players to be focused in on. And I want that to be on a daily basis, not just in games. Games reveal where you are and tell you what you need to work on. I’m more concerned with the attitude and the approach; I want that to be good.
‘‘I think if we’re doing the right things each and every day and everyone is putting everything they have into it, we’ll improve. I don’t think we can ever lose sight of how hard we’re going to have to play to be successful when we’re short-handed.’’
