Miami Heat star swingman Jimmy Butler was critical of his team's performance in their Game 4 loss to the Milwaukee Bucks on Sunday.

Butler said the Heat failed to execute and do all the little things they had done all series, noting it was a “bad” game.

Butler also agreed with Bam Adebayo's assessment when he was asked if he felt Miami played with less passion:

“Yeah, I think so. I think that was it,” the Heat vet said, via ESPN's Nick Friedell. “We did what we always say we can't do which is get comfortable. We thought this one was going to be easy and it was not … so going into the next one we just got to put them away.”

The five-time All-Star had been a major catalyst for the Heat in the first three games of the series, averaging 27.7 points, 4.7 rebounds and 4.7 assists while also putting up a whopping 13 free-throw attempts per game.

However, Butler struggled on the offensive end of the floor on Sunday, finishing with just 17 points on 6-for-15 shooting from the field. He still had a tremendous impact on the game defensively, finishing the contest +4 in terms of plus-minus.

Butler, nonetheless, suggested he and his teammates lacked the desire needed to finish off the Bucks.

It would be a surprise to see the Heat come out flat-footed for Game 5, regardless of whether Giannis Antetokounmpo takes the floor for the Bucks. Jimmy Butler is one of the consummate leaders in the NBA, and he will almost certainly have his team ready to go on Tuesday.
