I personally have been higher on Kaufman than Furst. However, being a legit player for Ingram (who I thought was taking a token visit for the most part) changes things and makes me think Furst is a better fit. Ingram looks similar to Malik Hall in that 3 / stretch 4 mold, but not having great quickness, so I think he'd be a little redundant with Kaufman. Plus, if Furst is on board to play some 5, I think that's where he can be really, really good.
And speaking of Ingram, it sounds like that visit went very well.
I'm really pleased if this news turns out to be Furst (which it is). If we can somehow add Ingram, this would be massive back to back classes for Painter when you combine the fact that Newman + Gillis RS puts them in there as well.
