Demar DeRozan was a man looking for answers after his Chicago Bulls were handed a demoralising 126-98 defeat at the hands of the reigning champion Milwaukee Bucks.

DeRozan, who at one stage this season was considered a real MVP candidate, had a sub-par 23 points on 23 field goal attempts in the loss, which moved the Bulls to a record of 3-9 in their past 12 games.

Three of the Bulls' past four games have now resulted in losses of at least 15 points against strong playoff contenders in the Utah Jazz (125-110) and the Phoenix Suns (129-102) before Tuesday's loss to Milwaukee.

Speaking to post-match media, DeRozan said it was evident what makes the Bucks a great team.

"Playing against the defending champs – seeing, feeling, understanding how hard they compete, and how well they execute," he said.

"Their physicality, everything that comes with it, it's how they got what they deserved last year, so that's what I take away from [this game].

"It's definitely not a talent issue at all – we've proven we are a great team – it's just execution, especially when you're playing against top-notch teams that understand the value of executing on both ends, and understand their assignments every time they stop out on the court.

"Those teams are always on a string, and we show it through spurts through a game, but the good teams that go far do it as close to 48 minutes as possible – not just a quarter, or half a quarter.

"You need to be as close to perfect through a 48-minute game as possible."

DeRozan went on to talk about the value of going through tough periods in the schedule when preparing for the playoffs, but stressed that the problems will not solve themselves.

"We're starting to understand what it's going to be like [in the playoffs] – it will be even tougher come playoff time – but we're going through it right now," he said.

"We've got battle wounds, or battle scars, and we're taking it all on the chin right now, so it's going to show us what we're made out of.

"It's definitely frustrating – we hate to lose, so everyone's mindset is frustration. We have to figure out how to channel that frustration to use on our opponents.

"Sometimes it takes someone getting hit in the mouth and knocked down before they get upset and fight back and come out swinging. You've gotta have that mentality before you get hit – you need to be the ones coming out swinging.

"At some point we have to get tired of getting our butt's kicked, and that switch has to flip, enough is enough, we have to show our desperation.

"Sometimes it's okay to go through [a stretch like this] if you let it build you up and bring that toughness you've been searching for – something like this can bring that out of you – we just have to find it."

The Bulls next play on Thursday night, when they make the trip to take on the surging New Orleans Pelicans on the road.
