That's the situation we're dealing with as the C's and the Boston Garden play host to Rivers' Los Angeles Clippers on Dec. 11, making it the first time the head coach has faced Boston since joining the franchise in 2004. Of course, it's a scene that will trigger plenty of memories.
After all, Rivers has quite a few highlights from his tenure with the Celtics. There are plenty of great moments, including—but by no means limited to—these 10.
From being hired by the franchise prior to the 2004-05 season to embracing one of his favorite players at the close of the short-lived 2013 playoff run, Rivers' time in the Garden was nothing short of remarkable.
He coached All-Star teams, won a championship and even joined an exclusive fraternity of Boston coaches.
But out of all the great memories, these 10 have to be the ones that rise to the front of his mind when push comes to shove. When he strolls onto the court in Beantown, think of these and the good times he provided rather than focusing on the bitter end.
