The Cleveland Cavaliers have struggled mightily against the Boston Celtics this season, consistently falling behind by large margins and failing to mount a serious comeback. Coaches and players have acknowledged a "mental block" that seems to prevent the Cavs from playing with their usual conviction and clarity when facing the Celtics.

Why it matters

The Cavaliers have emerged as one of the top contenders in the Eastern Conference, but their inability to compete with the Celtics raises questions about their readiness to challenge the league's elite teams in the playoffs. Overcoming this mental hurdle could be crucial to the Cavs' championship aspirations.

The details

In three games against the Celtics this season, the Cavaliers have fallen behind by at least 20 points in each contest. Despite having a talented roster led by Donovan Mitchell and James Harden, the Cavs have looked hesitant and reactive against Boston, struggling to find their rhythm on both ends of the floor. The Celtics, meanwhile, have maintained their composure and executed their game plan without seeming fazed by Cleveland's attempts at a comeback.

What they’re saying

“I think there is a little bit of a mental thing there. I think there is a mental thing of playing against the Celtics that there's just more pressure that you feel. They apply a different kind of pressure to this team and they haven't figured out how to best deal with that.”

“One team is incredibly comfortable and unfazed, and the other one is on their heels almost the entire game. It's been three games against the Celtics, and the Cavs have been down by at least 20 in all three of them. That that shouldn't be the case.”
