The Miami Heat broke its franchise record in 2014-15 by using 31 different starting lineups (They used 30 starting lineups in 2008).
Although not the only factor, injuries were a big reason for the Heat’s lack of continuity, notably that of Chris Bosh and Josh McRoberts.
McRoberts played only 17 games in the 2014-15 season with a knee injury, while Bosh played 44 games before blood clots sidelined him for the remainder of the season. As a result, for a majority of the season, the Heat had to rely on players like Hassan Whiteside, Henry Walker, Chris Andersen, and Udonis Haslem to pick up the slack.
