Mazzulla says the pressure on the Celtics is coming from comparisons to Cavs and Thunder: "Oh, you're not as good because you're not them."

When speaking to the media following Boston's loss to the Raptors, Mazzulla admitted that his team isn't reaching its full potential. The third-year head coach noted how the Celtics aren't playing at their best and that improvements are needed if the team wants to keep pace with a chasing crowd.

While the Celtics have produced an excellent record so far this season, they haven't been the dominant force many expected as they defend their NBA title.

During a recent news conference, the Celtics head coach discussed the difficulties and importance of finding minutes for younger players looking to improve their game. He explained the balancing act it takes and why it's a high priority for the team to ensure a pipeline is in place.
