They all claim 1 and 2, but the proof is in the pudding. Even if true, there's a difference between that and wanting to be a part of it.
Probably true on 3, but the uncertainty over Leonard's health has to concern him and Aldridge probably holds virtually no appeal. In this era, perimeter superstars and stars want to play with finishing bigs, not featured ones.
I wouldn't be surprised if Leonard is at the top of the list of players he'd like to play with, but he's not coming here to do so. If he becomes available via trade, maybe through the back channels his representation lets Johnson/Pelinka know that he'd be interested if they trade for him.
Although in conference, it's possible the Spurs would prefer the certainty of a package including Ingram and Kuzma as opposed to Fultz, especially considering their supposed strong belief in Murray becoming a star.
