MILWAUKEE — The NBA’s elite teams almost always have a singular, defining trait.Golden State gives opposing teams headaches due to its ridiculous outside shooting. Cleveland’s players, as LeBron James and Kyrie Irving illustrated during the Finals, can get almost any shot they want in one-on-one matchups. The San Antonio Spurs, the gold standard for team play and consistency, have long drawn praise for their lack of egos.Then there are the 18-16 Milwaukee Bucks, who, bizarre as it sounds, are quietly building a case for inclusion onto that short list of the league’s best teams.As of Thursday, Milwaukee was just two games ahead of the ninth-place Washington Wizards and far from a lock to reach the playoffs.
