This offseason will be a lot like the last one for the Boston Celtics.

Except they're another year older.

Kevin Garnett and Paul Pierce could be heading for retirement. Coach Doc Rivers also wouldn't commit to another season with the Celtics after they were eliminated from the playoffs Friday night with an 88-80 loss to the New York Knicks in Game 6 of their first-round series.

Pierce will be 36 when next season starts. The Celtics captain says it will be up to general manager Danny Ainge to decide whether to keep the team together for another season.

Garnett turns 37 next month. He says he will base his decision in part on what Pierce does.
