I understand your point - and guess its how you interpret poor (and maybe a poor word choice). I meant that for elite recruits, he is below the mean in that category and leaves something to be desired. I don't really think there are that many great players who aren't very athletic, unless they hold some other significantly above average skill or trait (i.e. 3 point shooting or height). Just consider why Jerami Grant was drafted in the first round - because a lot of basketball minds really value athletic ability, as it certainly wasn't for his jump shot.
Again - the staff does an excellent job of evaluating talent and I'm basing my opinion off some highlight reels - but its what I see. I know its popular to just drool over every recruit but differing opinions should make this more fun - if its any help I really like all 4 players in the class of 2015 (admittedly some more than others!)
PS - I know you weren't comparing him to Melo, but I do think Melo is a great athlete. Great first step and gets off the floor quickly - hence being a great rebounder for his size.
