Indiana Pacers head coach Rick Carlisle on starting Siakam at center against the Miami Heat: "Well, you look at their lineup and the level of skill and athleticism and everything else and Bam, he's a unique guy at five. He's a five that has three skills and so that matchup is a difficult one.

"All the matchups led us to the conclusion that starting smaller was definitely a better idea defensively and we hoped it would work out offensively, but it seemed to work out. We got off to a good start, but as the game went on, there were a lot of adjustments that were going on with substitution patterns."
