I'm a little worried people are overrating how good Hernangoatmez can be, because he has some physical limitations that set a ceiling for him... but yeah - this is a solid young core. And if Dotson turns out to be a player (he looked like he had NBA tools this summer) all the better.
If you are a Knick fan, and you want to enjoy the season - you should start of understanding they're not a playoff team - take heart watching young guys develop (giving somebody like Frank a long leash) - and then hope for a top 5 pick.
I think Willy has quality starter potential but it comes down to his defense. His offense and rebounding are already pretty polished. The real issue I see with him is that KP is closer to a full time Center than I expected and one of the two would need to chase PF's around the perimeter to make that front court work long term. Willy's supposedly cutting weight and he does cover the rebounding side of things so KP wouldn't have to, but on defense they'll need to figure out a creative way to make both guys work together otherwise Willy is a quality bench piece. That said...his contract is so damned beautiful, one of the best moves of the PJax term is not just getting that pick but also the contract agreement afterward.
All that said, I know what you mean. The Marc Gasol comparisons only make sense in that Gasol was underestimated and not in the best shape. I don't think weight-loss will have such a pronounced impact on Willy, it happens with guys but not with such a massive impact. If there's anyone I'm eyeing for getting into better shape and becoming a better prospect, it's Caleb Swanigan whose game I'm massively partial toward.
Edit: P.S. I'm coming into this season the way I was looking at the second half of last season. Give the keys to the kids and let what happens happen. If they sink we pick a Doncic, Porter or Bagley and if they swim we've got a young core to enjoy. This is a year to enjoy how players develop and handle bigger roles moreso than anything else and I hope the majority of fans realize that.
