MILWAUKEE -- Dwyane Wade doesn't look or sound worried. Having been in the league for almost a decade and a half, the future Hall of Famer has experienced all the highs and lows the NBA can offer. But after watching his team coast through parts of yet another loss, this time a 108-97 defeat at the hands of the Milwaukee Bucks, Wade brushed off the concern question, despite the fact the Bulls have lost five of their last seven games.

"I'm not concerned," Wade said. "I've been through everything; you might want to ask somebody else that. My 14th year, this is my first season here. I'm learning this team, learning these guys, so I'm fine. Obviously, it stings that what you see happen in the games you want to correct, but you got to go through the process, as we say. We're learning how tough it is to win in this league, no matter if you're on the road or at home.

"We're also learning how to win some of these good games, so it's just the season that we're in ... [We] understand that if we continue to learn, continue to do things right, we will go on a streak, we will go on a strand when we're putting games together. But nothing concerns me in this league at all."

After watching the Bulls sleepwalk through the first half on Thursday night, a game after blowing a 21-point lead to the lowly Minnesota Timberwolves, Wade seemed to be the only one in the locker room who wasn't worried. The script remains the same each night lately. If Wade and/or Jimmy Butler don't carry an enormous load offensively, the Bulls don't win.

Rajon Rondo returned after missing Tuesday's loss because of an ankle injury, but was a nonfactor, scoring just five points, dishing out eight assists and committing three turnovers in almost 30 minutes. The Bulls' bench was once again a weak spot, as Bobby Portis and Denzel Valentine, both of whom did not play Tuesday, combined to go 3-for-12 from the field. Wade ended the game with 20 points, but he was a minus-28 in 33 minutes.

"Early's not an excuse," Butler said. "I just think that we have to know situations and what to do whenever the defense is doing this. That's just in the half court, but I think we didn't get back for the first half. We didn't defensive-rebound the way we were capable of in the first half, which led to their easy points. We turned the ball over a little bit too much. Everything's easily correctable whenever you look at it. But you got to go out and you got to execute that whenever you step out on the floor."

The Bulls haven't been executing well, but what has to be even more concerning for Fred Hoiberg is that there are far too many stretches when this team just goes through the motions. Hoiberg tried to shake things up on Thursday by leaving Niko Mirotic, Jerian Grant and Isaiah Canaan on the bench the entire game, but the problems remained. The Bulls had a nice stretch in the fourth quarter when they found an offensive rhythm, but it was too little, too late for a group that created a 27-point hole for itself earlier in the game.

The Bulls remain hopeful that Michael Carter-Williams (wrist) will return soon, but his presence isn't going to be what cures the Bulls if they continue playing like they did against a young and more athletic team like the Bucks.

"Tonight, we played the fourth quarter the way you have to play the entire game," Hoiberg said. "We'll continue to stress it. We'll continue to work on it. And we need to improve if we want to have a chance to win games this year."
