Whoa - step away from the KD comparisons please. Kid doesn't have the frame nor fluidity, KD was a one man show in college and lock for NBA superstar.
Holmgren is Shawn Bradley if Shawn Bradley liked basketball. He can be or become a dominant college player. Should be a fun season and if he can stay healthy might be the ticket for Gonzaga to finally win a title.
Holmgren oughta stay in college 2 years, cuz whenever he goes to the NBA the combo of size and strength of opponents is going to be a huge problem. Like Bradley, everyone will want to dunk on Holmgren. I dunno how old he is, my stay 2 years opinion is entirely based on when can he add that next 15-20lbs as he grows from teenage body to man body. He needs to do that and stay healthy. Ultimately I think his comp will be either Sam Bowie (couldn't stay healthy) or a poor man's Ralph Sampson.
Skinny, bony, anemic - yeah that can be said but he is so much different from Bowie or Sampson.
The kid can handle the ball like a PG, passes extremely well and has the range that Sampson, Bowie and all but a selected few can wish to have.
Will his frame find it difficult to deal with the bigger men he will see in the pros at his career start? yes but he will learn to work around it and any coach worth beans will find a way to fit him in on the court.
You are entitled to your opinion and I respect your views, however, I see a lot more upside on this truly unique talent than you. Yes I see similarity to KD in some areas but this kid will mix it up underneath - KD is adverse to rubbing elbows with anyone bigger than he regardless of his "frame"- the kid doesn't have KD's flash in an open or lightly contested drive to the hoop and the mid range jumper that KD has but KD didn't look like the KD now when he was 17/18 either.
Time will tell
