PG is very likely to leave a year from now.
No he wouldn't be.
George has never once publicly stated anything about where he wants to play next year. It's been reported (rumored) he wants to play in LA. And it is probably true he wants to play in LA, but that doesn't mean LA is the only place he will consider playing.
On the other hand, George has in fact publicly stated his desire to win, his appreciation for the Celtics culture, his desire to play with Hayward, and even retweeted a Pierce tweet that Boston should trade for George.
There is every bit as much indication that he would be happy playing for a contender in Boston as there is anywhere else.
People really need to stop with this false narrative that George will only consider playing in LA and nowhere else.
