Kyrie in Cleveland was a bad situation period. The fanbase, the city, just a shitshow. Hard to grow for any rookie who essentially was supposed to fill in the gap for LeBron and live in constant reminders of the past. Not many players in the history of the NBA have been able to come in, and without help, be the face of a team and lead them to a winning record(not CF or even Finals, that needs help or a special designed team). Rookie Jordan was on a 38 win playoff team, and LeBron was on a 35 win lottery team. Not a GOAT comparison stat, just showing how hard it is to go from the bottom to the playoffs in one season with a rookie star. *Iverson 22 Wins. Rookie Kyrie = 21 wins. Not everyone can do what Larry Legend did, especially post-merger.
I'm not a Kyrie fan. Kind of would like to see him fail to be honest. But if I wanted to be fair, I can see his side of the story too. Don't need to like the player, but I can sympathize a bit with his shortcomings and think Boston might actually be better as a playoff team with him than IT. Regular season, maybe not. Jae was a great glue guy, so that needs to be factored in too, just too many new faces to instantly click and have chemistry.
The change of scenery and new layer in the LeBron rivalry will be good for the league. More people will tune in to see the first Cavs vs Celts game, than Cavs vs Warriors. *barring key injuries, of course.
