Why are people saying "it didn't work out, so trade him"? That's an absurd take.
Kyrie is obviously a bit hot around the collar for being asked the same questions he's been asked since he's been here, questions he answered back in October. He's not going to come out and say "I'll devote the rest of my career to the Celtics no matter what"; it just doesn't work that way.
What's new in what he's said recently? The "I don't owe anyone..." comment was obviously taken out of context, and once the entire quote was printed was obviously directed more towards the media. He didn't throw his team under the bus; in fact, he reiterated that Boston is on his list, and is actually high on his list. But he's also going to be a free agent, and things can happen between now and July 1st that could cause him to change his mind, which is his right. He's going to put his interests first, which is the same for Every Single NBA Free Agent. As it should be.
If someone suggests trading him because "it didn't work out", please highlight what didn't work out. If it's the fact that the team is not favored to win the championship this year, then we as fans will likely be frequently disappointed in both the near and distant future.
