Kind of feels like a strawman argument debating another straw man. Yeah, there were some people who criticized KD for taking the easy way out, but the main issue (for me) was simply that it made the league less competitive and interesting. I don’t begrudge him making his own decision about where he wanted to play.
As for Irving, I don’t begrudge him wanting to leave, or wanting his own team. I simply don’t think he’s as good as he thinks he is, or that he can be the best player on a team that gets past the second round (if that). In other words- either he’s not going to be the face of the franchise, or he’s not going to win much, in my opinion. If he wants to do it anyway, go ahead, it’s his decision.
Having said that, there’s a difference between feeling dwarfed by Lebron, and needing to be the face of the franchise. If, as might be the case, he would be fine playing with someone like Harden, or Kawhi, or Anthony Davis, or many others who don’t cast nearly as large a shadow, he might be able to find a better situation.
