During the season, coach and general manager Don Nelson started to experience a rift in friendship with Bucks owner Herb Kohl due to personal disagreements with Kohl on how to run the team.
During Game 4 of the 1987 Eastern Conference semifinals between the Bucks and the Boston Celtics, Nelson controversially announced to the local and national sports media that he did not expect to return to the Bucks after the season was over due to said rift with Kohl.
Nelson would in fact resign after the Bucks lost the series to Boston in seven games, coming back from being down 3–1 in the series only to lose the seventh and deciding game in Boston Garden.

The Bucks hired Nelson's assistant coach, Del Harris, to take over the team for the 1987–88 season.
