The two-time defending champions lost their opening game against the Indiana Pacers, but levelled the series with a 87-83 victory last night.
The forward told reporters: "It's not going to be pretty. Not in the Eastern Conference. It's never pretty basketball in the Eastern Conference.
"It's about who can sustain runs. You know, who can get defensive stops? Who can not turn the ball over and who can get great shots? I think we did that in the fourth."
The Heat will host their first game of the series when the teams meet again on Saturday.
