I lean towards agreeing with you. Wouldn't be upset at it though. I think generally we want to use the space to sign talent where we can and figure it out later. The back end of his deal would be soft with the rising cap. I'm kind of cap illiterate though, so I really don't know who the Jazz would be competing with to sign him, obviously the Raptors, but I don't know who else has money out there and needs a PG.
FVV at least fits a need more than Kuzma (just to compare another gettable high priced UFA) does. He's also an advanced stats darling on an underachieving team which might suggest he can do a lot better on a better team construct.
