If the title defense fails, will the Celtics sink?

The Celtics' playoff journey ended today. In the sixth game of the Eastern Conference semi-finals, the Celtics were in a sluggish state. They were behind in the half-time game. In the end, the Celtics lost their opponents 81-119. The Celtics' defense journey was officially declared a failure. In addition to the failure to defend, Celtics general Tatum was also seriously injured in this year's playoffs. The 24-25 season really caused heavy losses for the Celtics. Will the Celtics, who failed to defend, sink into the trap?

The Celtics' championship win in the 23-24 season has a lot to do with the outstanding performance of Holiday, Porzingis and Horford. However, the situation of Holiday, Horford and Porzingis this year is actually not ideal. The Celtics' salary has exploded now, and they may not be able to make the so-called lineup reinforcement. Will the Celtics make some trades this summer to release the team's future salary space? Celtic fans may have to accept the reality that the Celtics will no longer be able to compete for the championship in the next few seasons.

NBA is so cruel. It is already a huge achievement to win the championship in the NBA today. No team in the NBA can achieve the title defense in recent seasons. Strength and luck are equally important for strong teams who want to achieve good results. After replacing the new boss, what adjustments will the Celtics' operating strategy in the future?
