I think the Heat are an excellent comparison for the Nets when it comes to having a "big ". The only way that worked, and remember it did not work the first year, was by Bosh sacrificing a lot of touches and Wade/LeBron coming to an agreement on how to share Alpha status. The Nets need to do this but I don't see any of them being willing to make that sacrifice. Kyrie left both the Cavs and Celts because he wanted his own team, Harden couldn't make it work with Westbrook or Paul and now he has 2 guys to share with, and KD, who is the most likely to be willing to do what's best for the team, is the LAST ones who should.
Plus there is a 50% chance that Kyrie's take on sharing alpha status is to show up in a wolf costume.
