If this trade happens, it will be very good for the Miami Heat.
Do you think this trade will happen?
I believe the trade is likely to happen since Lillard has expressed his desire to leave the team. It wouldn't make sense for the Blazers to keep him if he wants to go elsewhere. They will likely engage in negotiations to find a trade deal that they consider fair. Currently, there are no other teams rumored to be involved in talks for Lillard, so it seems that he specifically wants to join the Heat. That's what we should believe for now.
The decision will still depends on Portland if they like to trade Lillard on his desired team since provably they will not agree to what he demand if they don't like the trade offers given by Heat. For sure Portland will find better players to add on their roster if Lillard will go since if they cannot get a good replacement their team will get heavily affected to the changes made in this free agency.
True, there are plenty of teams that would go after Lillard with a better offer, so it is highly unlikely that he will be traded to the Heat if there's a better offer, as the Trail Blazers management is always the one to be followed.
