After winning the NBA championship last season, the Bucks have scuffled with six losses in their opening 10 games.
Khris Middleton, the team’s second-leading scorer, has been out for the last four games after testing positive for COVID-19.
In the Bucks’ most recent game, they fell 101-94 to the Washington Wizards, the first stop of a five-game road trip. “As long as we’re building good habits, I’m seeing guys taking shots they’re supposed to take, guys diving on the floor, rebounding the ball, making the right play, that’s what we need to care about.”
The Bucks visited the White House on Monday and met President Joe Biden as they were honored for their championship.
