I'm probably one of the posters you're thinking about
And I don't think the ATL sendback (25, 26 swap, 27) plus the CHA (highly unlikely to be a first) and even the CHI pick on top would be an unfair deal.
The CHI pick is top 10, top 8, and top 8 protected and then becomes a 28 second. So at best it's a #9 pick. Pretty good, if the Bulls don't tank their way out of it either intentionally or via incompetence. And they are close to being bad enough naturally with a current executive structure that doesn't know what they're doing. And if they're fired, the new regime would be incentivized to tank even more.
And I wouldn't include Keldon unless getting back something else like Hunter. Hunter is hurt all the time and overpaid but closer to an SF archetype.
So if someone thinks Young is trash or bad, then no price is worth it due to his salary. Not even 1 pick.
But if someone thinks he is legit and can pair with Wemby well, then it's fair to look at the value of the picks when low on top of high.
Even if the Spurs 'overpay' they still have some caproom and other firsts like their own and other swaps plus tons of seconds, and seconds are the current currency for getting bench role players in trades.
