Enter: the New Orleans Pelicans.
Dell Demps is a nincompoop and may very well be fired at the end of this season. As a result, I could see him being inclined to make a heisty move that mortgages the future in a win-now trade that he can sell to management. They'll still miss the playoffs but a deal that revamps their starting lineup and help them finish strong, heading into next season, might buy him some time to continue collecting paychecks. If I'm Phil, I try to leverage that situation to further my team goals (which should be to find another Porzingis in the draft and simply rebuild).....
There'd be more moving pieces but, in effect, I'd send Melo to the Heat; Dragic, Deng and Lopez to the Pelicans; and I'd bring back expirers, Justise Winslow and the Pelicans' unprotected 2016 first round pick.
The Heat do it because Dragic is useless to them, while Melo fulfills their need for more scoring/consistent play from the 3-spot. The Pelicans do the deal because they are idiots and will continue to shoot themselves in the foot. We do the deal because it accelerates a potential rebuilding process around Porzingis.
That Pelicans pick is slated for the 6th spot in the lottery, which still offers a decent chance of getting the no.1 overall pick and walking away with Ben Simmons aka LeBron James Jr. Even though the Pelicans would significantly upgrade their roster, they'd still be every bit as injury-prone as before, which means that they'd still continue to lose games, in a still competitive Western Conference. When you factor in the growing pains that accompany overhauling the roster, there is a chance that the pick could continue to improve in value, especially with Brooklyn looking to win-now (since they sent their pick to BOS).
Long story short, we should roll the dice and try to get Ben Simmons to pair with another rising star in Kristaps Porzingis (and Justise Winslow). Can you imagine how amazing that (SF-)PF-C tandem would be?!?!?! Gives me goose-bumps just thinking about it.
