People always say this, but forget a few factors that I think are important
Bron would not commit past those basically 1 year deals with the Cavs. You’re asking Kyrie to keep his wagon hitched to a team that could essentially blow up at any time. I don’t think he wanted to be stuck there with years left on his deal if Bron suddenly decided to leave. Yeah you can “trust” that he’d be there as long as you were, but that honestly isn’t the proper way to manage your own career. If it wasn’t Kyrie, I think more people would acknowledge that.
Let’s be real, they were absolutely dangling him for Paul George. Again, Kyrie was to put his future in his own hands in case shit went south. Regardless of how it ended, Boston was a better landing spot than wherever he would have gotten traded to if the Cavs wanted to switch things up.
They were not beating the KD Warriors. Let’s be real here. The Cavs had maxed out the utility of the Bron-Kyrie-Love team. Getting to the finals and losing to the Warriors was best case scenario for the Cavs, so I don’t blame Kyrie for thinking it was time to go.
I really don’t see the point in Kyrie even staying unless he wanted to be a Cav long term after Bron left or he thought they had a shot at another title, and I don’t think either of those things are true.
