Who could take Utah's last spot?
With the players now having signed on the dotted line, the Jazz have one roster spot left. Technically, they don't have to sign anyone to meet the NBA's standard for roster spots filled in. However, they could still use this to their advantage.
The Jazz could get an asset out of that last spot. They could do this by acquiring players with little value from teams who have no use for them.
There wouldn't be much point to acquiring them besides getting another draft asset or two, but knowing what the Jazz's intentions are, that can't really hurt them.
