Bobby Marks did a Raptors offseason analysis that talked about FVV a lot. The cliffnotes:
-FVV turned down a 4-year $114 million extension (that's a hair under $30 million per year on average, so I would imagine he declines his option and hits free agency)
-FVV has played the second-most minutes of anyone in the league over the past three seasons.
-FVV leads the league in miles covered per game over the past three seasons
So you gotta pay him well above $120m/4 seasons to get him, but he is about to turn 30, is one of the smallest guys in the entire league, and might grind himself to dust.
I don't know about the whole thing. On the one hand, the Jazz are positioned to roll some dice in free agency with their cap sheet the way it is, an influx of rookie-scale players, and a cap lift in 2025. On the other hand, there is still the matter of opportunity cost: the Jazz don't have infinite opportunities to roll dice, a wasted roll takes some serious ammunition out of the chamber. That cap sheet merely allows them to survive without jettisoning assets if it goes bad (which is better than the alternative), but it could also be a millstone that prevents the team from reaching its ceiling.
Players in their 30's drive me nuts when trying to anticipate their trajectories. Some guys are effective well into their mid-thirties, and some guys fall of a cliff over the course of one or two seasons. But if you're assessing a player, you can lean on good shooters and players that have plus size for their position (and might be able to shift up a position to compensate for lost athleticism). FVV has the former but has **** all for the latter.
