What's there to address? You'd give up whatever the other team wants, that's not a musical wish. If they want Olynyk and won't budge, you'll either give up Olynyk or not do the trade.
Really? You make it sounds like GMs are calling Danny offering their stars, which is almost certainly the opposite of the truth.
In reality, Ainge is the one building packages to offer for the likes of a Butler, Griffin, Cousins, etc. So he is in fact having to prioritize his assets based on existing skill set, potential upside, contract, health and team structure... then making proposals, not calling GMs and asking them to bid against themselves.
So the point you belittle remains. It's in the Celtics court to entice opposing GMs to trade their veteran players. My argument is that Olynyk is likely the most attractive externally of the rookie contract assets, along with Smart. And I believe the Cs would rather trade KO than Marcus, unless they're trading for a starting guard.
