I agree with you on Lavine, but the kid can straight up knock down 3s. Boy has deep NBA range. I'm not even talking about wanting him due to huge upside and athleticism. I could careless about that.
I'm a fan of Payton, but Ennis is a day 1 starter. Much safer pick and high basketball IQ. Size is the only concern.
If you could care less about his upside and athleticism, why not take Mcdermott or Staus instead? They both are better nba range shooters.
For me, unless someone irresistible falls, I take Mcdermott at #9. Completely sold on his scoring impact and he would have a positive impact on his teammates due to floor spacing. You can't leave him alone.
At the very least, he will be a 40%+ 3 point shooter, but he can do so much more offensively.
