Not even Boston Celtics owner Wyc Grousbeck knows where his team is headed this summer.

Grousbeck told WEEI's Mut and Merloni on Friday what the NBA world figured: The Celtics are entering the offseason with a number of ideas, but no set direction.

The Celtics have just four players currently under contract for next season. Kevin Garnett is contemplating retirement, and his decision on that front could be the first domino of many to fall in Boston this summer.

Via WEEI:

"I think it's fair to say when you look at the roster and you see who is under contract for next year starting with [Rajon] Rondo and [Paul] Pierce, and then you see who isn't under contract -- obviously a number of very good players are coming off deals with us including all the way to Brandon Bass and [Mickael] Pietrus and other people opting out or being free agents -- the picture is not in place for next year yet," said Grousbeck. "There are free agents available this summer as well from other teams, and there are a bunch of free agents available next summer from other teams, potentially.

"We can let this play out. We want to stay competitive. We want to stay contenders if we possibly can, but we really want to get banner 18, and sometimes you need a lot of luck to get a banner, I can tell you that. But we will see how this plays out over the next couple of years."
