Holmoe's #1 pick in the first place and (2) Oregon State had no talent at all so you can't judge Kalani by his one year there. They also said (and I agree) that it would have been fair to give a lower grade due to inexperience, but not for the reasons listed.
Also, my own thought is that, just because someone isn't #1 doesn't mean they are less worthy. That's like saying, because Lebron is so good, Curry is just average.
