Doc Rivers and the Boston Celtics won the 2008 title together and very nearly won again in 2010.

The Celtics were unable to fully defend their championship in 2009 due to an injury to Kevin Garnett. Garnett remained an effective player, but clearly limited after his initial season with the Celtics.

"I swear if Kevin would've been healthy, we would've won two or three in a row," said Rivers on Wednesday ahead of his return to Boston.

"I wish it could have ended better," said Rivers.
