Kaminsly has the best set of offensive skills for a big man in the draft right now. Good 3 point shooter, decent athleticism, decent passer, and decent ball handling skills. His weaknesses are his inside defense but hell prolly play a stretch 4 in the NBA.
Dekker is too inconsistent at shooting to be a good NBA player cause his athleticism makes him a good defender and a good slasher wing, but if he can't shoot consistently hell be like JR Smith where he won't really add to a team, but be a threat enough just by existing.
If Kaminsky or Dekker were euros they'd be in the top 10 and maybe top 6-7, but since they are white dudes from Sheboygan Wisconsin they get hated on. Dekkers upside is much more limited cause his game doesn't gel with the current NBA like Kaminsky does.
