I'd say a reasonable floor would be Toni Kukoc.
A reasonable ceiling I'd go with with Dirk Nowitzki.
I'll tell you what, man, if he's anywhere as athletic as Tony was, we just need to sit back and enjoy the ride. Bulls fans need to be wishing that Niko can man the 3 spot. If so, watch out, imo!
We'd have an international Tri Towers. Pau ay 7'0" can legitimately post up and score. Noah is Noah at 6'11", and Niko would be a sharp shooting 6'10" SF. That gives me a pudgie. Now, put defensive guru Butler on their best scorer, and, HOPEFULLY, let Rose create havoc everywhere else.
Then, the bench mob! Taj as 6th man again, the thunder from down under at C, Dougie Fresh and Snell drilling 3's on the wing, and Captain Kirk navigating the starship!
Fuck Yeah! I need a beer.
