I I tend to agree somewhat with what you r saying..you have to have some ability to go with that size. The big problem is most who have reached that size as a teenager are still learning coordination for such size. I had a somewhat similar view of Perkins from my very limited times of seeing him in high school, he seemed to be "dominant" mainly by size at at point not by his ability. Size is a huge part of why they get the attention from scouts but they also have to show signs of are talent as well.
