The Warriors and Celtics will face off on Friday night in Boston.
Outside of TD Garden, fans can buy merchandise, including a shirt that reads: "Durant is a b----"
During free agency, Durant met with representatives from the Warriors, Thunder, Clippers, Spurs, Heat and Celtics.
Boston's owner Wyc Grousbeck believes the Celtics were the runner-up in the Durant sweepstakes.
As CSNBayArea.com's Monte Poole wrote on Friday Morning:
"It won’t be as loud or as chilly as it will be when Durant and the Warriors go to Oklahoma City in February, but this could be the first place where they feel the animosity expected in the wake of signing Durant.
"Being so close to adding Durant, after signing free agent center Al Horford, had Boston and Celtics fans thinking big."
“What can they be mad about?” Durant told reporters after the Warriors 127-121 win at Toronto on Wednesday. “I never played there. I never said I was going there.
“They’re going to support their team. That’s one of the best fan bases in the league, top-five easily. No matter who goes in there, they’re going to boo them. But I had no attachment to Boston at all."
