I'm not sure about Holmgren in many areas, but I am pretty damn sure the idea he can guard NBA SF's and wings is loopy. As some have said, I think he'll have lots of trouble, in lots of games, defending NBA PF's. Guys like Giannis and Siakam and Jackson will eat him up
and a lot of NBA C's will simply push him all over the floor. Holmgren will be perpetually in foul trouble at C, at least he will in his first few seasons
I would agree that it's kind of hard to come up with comps for him. KG is a bad one, IMO. Durnat is a ridiculous comp. I think Porzingis is closer; he was/is a similar type of unicorn. And Porzingis is a good comp in another critical way: his impact has never been significant because he's an awkward fit for the modern NBA. Seems like in order to be an impact player as a C, you need extreme elite talent like Jokic or Embid or KAT. That's not to say that lesser talents can't have impacts at C; there are plenty of guys at the level of an Ayton, Sabonis, or Valanciunas. I mean, think about guys like Sabonis, or Nurkic or Valanciunas....how many years in the weight rooms would it take before Holmgren wouldn't be pushed all over the floor by those guys?
and if he's a PF, is there really any chance he ever becomes an elite player? How many top-20 NBA players right now are PF's? I'd say there is only one and that's Giannis. That is a really difficult position from which to create high-level impact
which kind of leads to something else: is Holmgren another project-big? and if he is how long will a team have to wait before he's matriculated from project to star?...if he ever does?
