But Kevin Garnett is six years removed from playing in Boston, and he has some thoughts about Irving's Celtics tenure.
During an interview Tuesday in New York to promote "Uncut Gems," a new movie he stars in alongside Adam Sandler, Garnett said he wasn't surprised that Irving bolted after just two seasons to sign with the Brooklyn Nets.
Why? Let KG explain as only KG can, via the New York Daily News' Stefan Bondy:
Boston's a tough town, dawg. You have to have some major cojones to be there. You got to want that. The people want it for you.
That's why Paul (Pierce) is perfect for it. Paul wants the shot every time. Like, ‘You're 0-for-14.' And he's like, ‘I know, but they WANT it.'
Garnett's implication is that Irving didn't have the "cojones" to play in Boston, and in a way, that's true: Irving expressed his frustration with the Boston media on several occasions last season.
"If they come to the city and dominate, man. … The first superstar to hit New York and be vibing is going to be bigger than life," Garnett said. "Remember I said that."
Garnett thrived in the Boston and Brooklyn markets thanks to his outsized personality and willingness to speak whatever was on his mind.
It's safe to say Irving was on the opposite end of the spectrum -- which is why KG could have predicted his "marriage" with the Celtics wouldn't last.
