The head coach told reporters: "Our bench, in the last three pre-season games and tonight, really just blew the game open. I think they're going to be really strong, I think it was just a matter of nerves tonight.
"We have to be dominant at home if we hope to compete for the one seed [in the Eastern Conference] with the likes of Brooklyn, New York, Chicago and Miami. You have to be dominant at home."
Indiana were the runners-up in their conference last season.
