FVV already got his bag and was grossly overpaid relative to his performance the past two seasons. We overpaid because we had cap space and wanted a veteran PG. Hopefully (LOL yeah right) FVV and his agent can be reasonable based on the money he already got and how much he'd likely bring on the free agent market. The only teams with significant cap space are Detroit, Brooklyn (who may get Giannis?), Philly, San Antonio, and New Orleans. Would any of those teams want to sign FVV for $30m? Would he prefer playing for one of those teams vs. staying with the Rockets?
Hit the google and there are multiple articles about how screwed free agents are this offseason, and even the really good fringe-allstar guys may get offers in the $20-22m/yr range. FVV could FAFO if he plays hardball and end up taking some team's mid-level exception. Houston may not be able to trade FVV unless it's before June 29 as salary filler (receiving team would just decline his option), because I doubt any other team will want to pay him $45m+trade kicker and I doubt FVV would agree to a sign-and-trade at <$25m/yr. I guess Houston could lie to him, resign him closer to market value then turn around and trade him.
