Former Boston Celtics head coach Doc Rivers is taking time out of his busy schedule with the Los Angeles Clippers to attend an NBA game as a fan on Sunday. That comes with the Cleveland Cavaliers set to take on the Celtics in Boston as the home team retires Paul Pierce’s jersey.

So what are Rivers’ plans as he attends this game? According to the Clippers’ head coach himself, he’s going to “grab a beer, yell at the refs all game and boo LeBron.”

To be honest, that sounds like a perfect Sunday in Boston.

Of course, the backdrop of this game includes LeBron James taking on his former teammate, Kyrie Irving, in Boston.
