Cavs player says “Danny Ainge is a (expletive) thief”

RealGM via The Athletic:
The Cleveland Cavaliers traded Kyrie Irving to the Boston Celtics last offseason in a deal at least one unnamed player on the team thought was not equal value.

“Danny Ainge is a (expletive) thief,” said the player after a loss during the regular season.

Any guesses on who that player is? The loss of Kyrie Irving is killing the Cavs right now. Trades are probably going to get even harder for Ainge to make as his reputation of winning them convincingly continues to grow. Even the trades where everyone thinks the C's gave up too much are turning out to be home runs for Boston (The Fultz trade, The Isaiah plus Nets pick for Kyrie trade, The Bradley trade).
