I like Young a lot, and before hiring Igor I wanted him more than anyone besides Ayton. I think he's the best fit for the Suns right now of any potential pick, Ayton included in that, but with Igor on board I think he knows whether Doncic can be a PG in the NBA. That's what worries me about him because if he's not a PG then we're stuck with 6th man because I highly doubt he'll be better than Booker or Jackson in 2-3 years. If Igor says he can be a PG, take him. He has a past with him so I'm fine with him making the call in that scenario.
I don't want to see the Suns get cute and try to trade down though. They should be able to drop to 4 and get Young still but the Suns have been burned too many times in the past for me to feel comfortable with trying to pull something to get the player they want and an additional asset. Getting the guy we want is more important than adding another asset to use later, whatever that might be. I doubt it would be anything we couldn't pass up.
New York did that with Porzingis a few years back and even though Knicks fans boo'd it when announced I don't think any of them would risk doing it over and trying to drop a few picks to get him and add something else, since he was not projected to go that high.
