Regarding about the trade, it seems that a 3rd party is needed on the trade and it's the Brooklyn Nets who surfaced amongst all teams who are interested to facilitate it because Portland have changed their mind and that they are now not interested in getting Tyler Herro.
Here's the Mock Trade:

It's funny. This site calls it "a perfect 3-team trade", but I'd say it's a perfect deal only for the Nets and the Heat but not for the Blazers. The way I see it, getting a few future first-round picks, as well as an aging Lowry and a weird guy like Simmons, would be a dumb decision by the Blazers' management. In that case, the Blazers would look like the Rockets, who have been trying to rebuild their team for a few seasons now.
That's what would happen if they give up their main players without receiving quality players in return. They might need to wait a little longer to rebuild their team effectively. It would be beneficial for Portland to acquire a star player, especially considering Lillard's desire to leave the team. As for the Heat, Jimmy could be a good trade option, but it remains uncertain whether the Heat would agree to such a trade.
We don't have a clue yet about what will happen, as the teams involved have already laid their cards on the table. However, it appears that Portland still remains uninterested in the situation.
