It won't happen because it's an absurd trade that is laughably one sided. (Hint - it's not for the Suns) Would you honestly make that trade if you were GM? Send the lynchpin of your D to Sac for 6'8 Holmes to start? I love Richaun, but he's the kind of guy the Suns need to have IN ADDITION to Ayton, not to replace him.
Haliburton is a nice piece, but again, it makes no sense for a team hunting for a ring now. We KNOW Ayton can get you to the finals.
I hope you know on the national level, your valuation of Ayton is considerably lower than most. The vast majority of people are very surprised Ayton didn't get his contract, and that's not to say that conventional wisdom is always right, but going against and failing can lead to embarassment.
Seeing people talk about trading him for unproven rookies or guys like Vucevic and Sabonis is truly puzzling. None of these guys can provide anything near the D that Ayton brings to the table, and that's where he provides the bulk of his value. That's where even a supremely talented offensive weapon like KAT doesn't make sense.
The nation didn't even notice us or give the suns any props/respect last year. I think a lot of us on here and the suns organization view Ayton the same, which is lower than the national perception.
