No idea why the Knicks would sign Hartenstein to a fairly bug deal only to misuse him, but that's Thibs for you. Love Vanderbilt, but Hartenstein fixes a major pain point of everything going to crap when Domas sits. Vandy can play some center, but he'd mainly take PF minutes from Lyles.
I like him more as a player, but Hartenstein is a better current fit. But that's if we had to decide between them. Depending on asking price, why not trade for them both?
