The Utah Jazz have 18 players on their team, 15 players on their main roster, and three more under two-way contracts. Of those 15 players, three are on non or partially-guaranteed contracts; Kris Dunn, Luka Samanic, and Omer Yurtseven. Meaning at any point, the Jazz can cut those men and not pay them any, or not all of the money their contracts are set at. It’s possible that for any reason, one, two, or all three of them may be cut at some point this season.
That or they may be involved in a trade. Should they, or anyone else on the 15-man roster, get traded, cut, or injured, the team will call on the two-way players to fill the gap on the roster.
