I don't see how MIA can make a fair offer unless they include Adebayo, which apparently, they won't. If I was POR, I would not settle for Tyler Herro and whatever not named Bam, no matter how many picks they throw in. If they can't get MIA to include Adebayo (Herro and Adebayo plus picks is fair), I go back to Lillard and tell him they tried with MIA, but it didn't work. Either add to you list of teams or suit up because we are not going to trade you to MIA for a bad deal.
I see them as still trying to do their due diligence with MIA. That is fine. That needs to play out. They can indulge Lillard and fully exhaust any possibility with MIA. But if that does not result in a fair deal, so be it. And I can understand why no other teams aren't really engaging until the MIA thing has played out. No reason to.
