Portland Trail Blazers
Honorable Mention: Deandre Ayton
The Utah Jazz could use Deandre Ayton if the team gives up on John Collins. Ayton's not better than Walker Kessler at this point, but if you need another big body, who plays alright defense, Ayton can give you that.
Malcolm Brogdon
There are a few guys that the Utah Jazz could use at guard over Kris Dunn and Collin Sexton, and Malcolm Brogdon could be one of those. Never a great defender, Brogdon is a good shooter. He's nearly a 40% career three-point shooter, so whatever he gives up on defense he can make up for on offense. He's not such a bad defender he's unplayable, he just won't be the guy you want to put on the other team's best guard.
Jerami Grant
The Utah Jazz could use some help at power forward off the bench and Jerami Grant could be that sixth man type player. The issue with him is that he's undersized and a terrible rebounder. Maybe that's not an issue when you have Walker Kessler on the court, but any other player may get Grant exposed.
Matisse Thybulle
As bad as Matisse Thybulle is on offense, he's even better on defense. Regardless of the direction the Utah Jazz take this season, Thybulle should be on the short list of guys they need. He'd make the team defense so much better even if it's by coming off the bench.
