I think NOLA makes the trade for Barrett. The potential for him to be a superstar outweighs the better players the Lakers may have whose ceilings are considered established.
It would actually be pretty funny if the Knicks could pull off that trade with New Orleans, and then sign him, KD, and Kyrie to long-term deals. That sounds to me like a team that could consistently win 50-55 games a year, and then implode in the playoffs because the hero ball shots didn't fall. They could fit in well in the new East, where all of the good teams have excellent players who can't seem to play together.
The only way JA Morant falls to 3 is if the Grizz are content with Conley still and want the wing player. I highly doubt it though.
