The Boston Celtics are staring down a pivotal offseason after an embarrassing playoff collapse, and NBA insider Brian Windhorst has some fascinating insight into what might come next. For the first time in franchise history, the Celtics blew a 3-1 series lead—this time to the Philadelphia 76ers—marking back-to-back disappointing postseason exits. The big question now: Is it time for a shake-up?

Should Boston keep its core of Jayson Tatum, Jaylen Brown, and Derrick White intact, or consider trading Brown to shake things up? And what about head coach Joe Mazzulla? With some cap flexibility after getting under the luxury tax, the Celtics have options, making this summer one of the most intriguing in recent memory.

On Tuesday's episode of "The Rich Eisen Show," Windhorst broke down the situation. "Now, they have to ask themselves in Boston, is this team that we have... can they still compete to win championships?" he said. "I think the answer is yes, but they may go through an evaluation period... I would wager on it staying together, but I don't think it's a no-brainer."

The Celtics also need to decide if they're all-in on their polarizing 3-point-heavy strategy—a style that won them a championship but has also contributed to postseason meltdowns. That decision will shape their offseason moves and the type of players they target.

One intriguing possibility? A Giannis Antetokounmpo trade. Windhorst noted that the Bucks superstar is only a few years older than Brown and Tatum, making him a potential fit for Boston's championship window. But if the Celtics double down on the three-ball, Giannis might not be the right piece.

With Brad Stevens calling the shots, all eyes are on Boston's next move. Will they run it back, or swing for the fences?
