There's a few reasons why Kyrie is taking a lot of stick from Boston fans, but the main one I think is that he basically ghosted us after promising us he was all in on being a Celtic. First his promise to season ticket holders "if you're willing to have me back, I plan on re-signing here" at the start of 2018, then his commercial saying he wanted his number retired. Add to that the fact that we as fans were a very optimistic bunch with high expectations at that time, we thought we would plug Kyrie and Gordon back into our ECF reaching team and would challenge the Dubs in the finals, with Kyrie leading the way.
We all know what happened. Kyrie starting throwing his younger teammates under the bus, he became the face of the frustrations within the team because he was the highest profile player and because he was willing to talk about it. Then the rumors about him wanting to pair up with Durant wouldn't go away and the media kept bringing up his free agency and he handled it badly. Then he promised us we would do well in the playoffs "because I'm here". Then when we got to the playoffs, he just couldn't (or wouldn't) deliver when it mattered.
So all that was bad enough for fans...then he basically just ghosted us and signed with Brooklyn, didn't say anything to Boston or about Boston. Jaylen Brown and Al apologized to fans, we didn't hear anything from Kyrie. Aron Baynes took out a full page ad thanking Boston for his time here. (Even Kelly Olynyk did so when he was traded to Miami.) Our last Boston-related comments from him was more about him, saying he hadn't been in a situation where "he" got hammered 4-1 in the playoffs and that "he" would learn from it. Nothing about the team. Then he just...disappeared. First we hear about him signing elsewhere is with his slickly produced "I'm Coming Home" video, where there wasn't any word about Boston at all.
So it felt not only like he ghosted us after being engaged without explaining anything, but also that he dissed us, dissed what it means to be a Celtic, all the history, respect for the jersey, all that stuff. And not only that, he just so happens to be injured when he's supposed to play in Boston for the first time after leaving (things that make you go hmmmm???) then he doesn't even show up on the bench! Obviously there's no rule that he has to be here when he's injured, but that just so looks like a chicken act. No wonder people booed the hell out of him.
I don't think Kyrie is a bad person. I think he's a wondrously talented basketball player. I don't think he means to be a bad teammate, and I don't think the Celtics think he is. I do think he struggles with manning up to things that are difficult (like having to explain why he broke his word). God knows a lot of people do. It's why he tries to avoid playing in Cleveland, or Boston. I'd be surprised if he played here in the next 3 years.
Of course he doesn't owe us any explanation (not even his long rambling defensive Instagram missive). Personally I moved on from him long ago and don't need any explanation (even though I seem to be the starter of this thread, in my defense it wasn't titled this when I posted it
). But think of how much better it would have gone for him if he had a) been much more thoughtful and introspective about the Milwaukee series loss, and to do what Al or Aron did, make some kind of statement thanking Boston fans for supporting him during his time here, saying it was a hard decision but he wanted to go home. People would be disappointed but nobody would begrudge someone wanting to go home. Or if he had showed up to take the boos and turned it into a laugh, I think people would have respected that. They probably would have still booed him, but not as much
