Erik Spoelstra wants to make sure history doesn't repeat itself.

"If we learned one thing from the 2006 title, it was that you need to continue to reinvent yourself and improve as a basketball team," Spoelstra said. "That year we brought the exact the same team back, we thought it would be the same path and same journey. It never is.

"It's always going to be different. And we ended up losing the first round and we were swept in four games. Another year later, we only won 15 games and we were the worst team in basketball and that's how fragile this game can be."

Miami signed Ray Allen and Rashard Lewis to add depth and three-point shooting to a rotation that includes Shane Battier, Mike Miller and James Jones.
