Sam Cassell failed to play in Game Six and Seven in the Celtics' second round series against the Cavaliers and claims that he's rested for the Pistons, according to The Boston Globe.

Doc Rivers has played Eddie House over Cassell as of late because of the unique offensive punch he brings off the bench.

"[He] told me I might not play the last two games just to get ready for the Pistons, so that's what I came here for, to play against the Pistons and hopefully the [NBA] Finals," said Cassell.

Cassell believes Rivers was doing the right thing.

"He played for [Gregg ] Popovich. I know that Popovich does the same thing. He gives guys rest," said Cassell. "I got four days of rest. I'm cool. I'm ready to take on whatever role I get. I'll play a little bit more next series. Four days of rest, I'm fresh. I'm cool."
