I'm sure you didn't mean it in that way, but this is phrased poorly. To say we let Kyrie go is unfair to the team because he was essentially sabotaging any trade value he had while wanting to leave Cleveland. I would have traded him out of spite to a garbage team. He should consider himself lucky we traded him to Boston.
Fair enough. But it's also true we had him under contract for two more years, and we let him out of that. Kobe Bryant demanded a trade, publicly, in 2007 and the Lakers managed to keep him. I'll try to, as Northcoast says, "give it a rest", but it still hurts that we let a player under contract bully us into a trade to our biggest East rival.
