LeBron James discussed how the frequent changes in the lineup have been difficult to adjust.

"It's been challenging not just for those of us who have been constants in the starting lineup but for those guys who have been in and out, not knowing if they're going to start or not," James said.

The Heat have started seven different players at center over the past two seasons.

"It's been a challenge for all of us," said James.

"At times it's been hard to get a rhythm starting the game or starting the third quarter. That has been a rotating door for the last two years, not just this series. There's Joel, C.B., U.D. at times, Ronny and Damp and Z. The list goes on in just two years."
