Successful team defense all starts with two important qualities: unity and trust. A team can have all of the athletic, strong and quick players in the world, but without that team unity and being able to trust one another, the defense will fall short of the ultimate goal. That playoff run in 2018 was based off grit, willingness and sacrifice. The Ewing theory, which proposes that teams are often better without their stars due to synergy and an increase in team-oriented play, was in full effect. In 2019, much of the season and the series against the Bucks was based off uncertainty, selfishness, and agony. Boston’s identity as having a defensive prowess among the best in the league evaporated once Irving joined the lineup. Irving never integrated himself in that with parts of the season looking as such:
During the majority of the season Irving’s defense wasn’t a glaring issue, but when it mattered most it became a liability. When the leader doesn’t step up on the defensive end, it can spark a domino effect on the rest of the team. There were times where it seemed as if he was just going through the motions and not giving the full 100% that is expected. Despite Stevens earning the reputation of a defensive genius, Irving clearly wasn’t about it, and him no longer out there will lead to an improvement on the defensive end.
