I've never known much about Porzingis - I just assumed by his height that he'd be a center, but it sounds like he is taller, slightly less coordinated Kirilenko. I don't think I would be all that happy if Danny traded way up for him since that would mean we gave up a LOT; however, I would be okay with him if he fell way down the draft board (which won't happen).
I suppose he could be a very good player, but I will be surprised if he has as successful of a career as Kirilenko (who did very well). Even though people keep saying, 'when he fills out,' his weight scares the heck out of me.
