Jayson Tatum and Joe Mazzulla aren't happy with the way the Celtics are playing, but they're also taking a positive mindset through it.

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.
