The current NBA champions sit second in the Eastern Conference behind the Pacers, who have an 8-0 record.
The 29-year-old told FOX Sports: "Yes, they do get our attention. They're playing confident basketball right now, but I still think we're the champs and we're going to put it together, we're going to be up there in the conversation very soon. We just have to put in the work right now.
"They have that chip on their shoulder, they have that hunger that we don't have because we won last year. So you have to find different motivations and make sure you're constantly challenging yourself when it's on the other side of the fence.
"Yeah, we take note of everybody. I don't really like to talk about playoffs and home-court right now. I understand why people would want to. I understand the urgency, but it's November, we have to take it one game at a time."
The Pacers host the Milwaukee Bucks tomorrow, while the Heat play the Dallas Mavericks.
