I'll be probably the only one on this. But, I'd sign Noah Vonleh and the price should be reasonable, if you can get 3 years and maybe a player option for the 4th, that'd be ideal.
He's still just 22. I think he's a good fit and has nice upside. If the Kings are truly in asset acquisition mode, which was reported before the draft, Vonleh is a great project. He's actually got more skill than most would expect, he can dribble has a crossover, the bulls let him take 60 3's in 21 games and he's been a good rebounder per 36mins his whole career. excellent character guy, strong high motor...
this wouldn't really be a going all in move though, this is more like speculating on a potential booming asset in the coming seasons. I like Caboclo but Vonleh would be a much safer player to throw a real contract to.
Vonleh is a potentially solid pair with Bagley IMO..
