The 34-year-old small forward told NBA.com: "I basically played spot minutes in the regular season and played just heavy minutes in the playoffs. I'm a 34-year-old right now with about a 30-year-old body, 28-year-old body. I feel great. I'm ready to play.
"[Winning a playoff game is] my whole goal. I have unfinished business here, and we're going to see how it plays out."
The Grizzlies face the Oklahoma City Thunder in the first round of the playoffs.
