No where near enough for Zinger.
He's the closest thing in this league to Anthony Davis and could be better in 5 years time.
To get Zinger you'll need the NY GM to be suffering from brain damage and a godfather offer of something like Brown+Smart+Tatum+picks.
In other words, never happening.
Phil Jackson just pretended to put Zinger on the table to scare him into submission- and he got fired for it.
Zinger is basically untouchable at this point.
Ask yourself, would you trade Porzingis for Smart+ some picks which *might* be top 5 in the lottery?
