Memphis Grizzlies
Santi Aldama
The Grizzlies may not want to trade Santi Aldama just yet, but the season is a bust and who knows what next year looks like for them. Their superstar is unreliable, and their team is quickly getting very expensive. Trading Aldama makes sense if they're looking to build around Ja Morant with draft picks. As for the Jazz, Aldama is a stretch four, with a good perimeter shot, and a solid understanding of how to play defense in the paint. Not a game-changer, but a guy who can make you better.
Luke Kennard
The NBA sleeps on Luke Kennard too much. Easily one of the best pure shooters in the league, Kennard makes the Jazz better in any hypothetical trade by giving them a sharpshooter who can play in the starting five or off the bench. Not only that, but he's someone who doesn't give up much on defense either. A solid defender isn't easy to come by these days and Kennard can be that for you.
Marcus Smart
The Jazz could've used Marcus Smart a few weeks ago but truthfully, Kris Dunn gives you a lot of what Smart does, just with a better shot. Smart's better on defense, but Dunn isn't so far behind that you can't get a lot out of him if given more minutes. Smart would still help the Jazz, however.
