Jimmy Butler said that the Miami Heat doesn't see themselves as underdogs ahead of their series against the Boston Celtics.

The Heat come into the series as the fifth seed, with the Celtics the third seed.

"We don't really use 'underdog ... I think we're supposed to be here. That's how we think of it. To me, to us, that's all that matters. We're not underdogs. We're competitors," said Butler.

Butler added that while the Heat think they are the better team, their biggest opponent is the bubble itself.

"We all think that we're the better team. We all think that we're supposed to be here. And that's the way that I think. ... We always talk about beating the bubble, I think we've done a great job of doing that thus far. So going into these games, it's about us. We're in control of our destiny right now," he added.

Erik Spoelstra said that it's difficult to take anything from their regular season matchups due to various injuries. 

The Heat played the Celtics three times on the second end of back-to-back games. 

"You almost can't draw anything from those games, because there are so many different moving parts that are different than they are now. Of course, both coaching staffs will continue to dive into all that. But something that really stuck out to me, when you start diving into the film, somebody's always been missing."
