2008 Celtics champion Ray Allen tells the tale of the mysterious guest in Boston’s locker room after winning Banner 17

You would never guess their identity.

Back when the Boston Celtics were celebrating their then-record 17th NBA title at TD Garden late into the night after defeating the Los Angeles Lakers, 131-92, star Celtics shooting guard Ray Allen looked over at one of the many faces they had been celebrating with in the locker room all night long.

The room had been packed full of teammates, friends and families, team trainers and staff, front office personnel and all sorts of Celtics-adjacent people in the media and beyond. But the crowd dwindled to the team itself and a handful of others as the night dragged into the early hours of the morning.

In an interview with ESPN, the former UConn standout revealed he suddenly learned the identity of a mysterious guest that had been celebrating with them that whole night, blowing his mind with the news.
