I agree with most of your points Bsk33, however, I just want to nitpick one thing that a lot of people say.
Not really concerned about the 6'7" or 6'8" size being that he has a 7 foot plus wingspan. You don't block shots and rebound with your head.
While there is some truth to this, a 6'10" guy with a 7 foot wingspan will be able to better rebound and block shots than a 6'7" guy with a 7' wingspan. This is because the 6'10" guy's shoulders will be 2" above the 6'7" guy's shoulders, giving the 6'10" a higher reach. While wingspan is very very important, it can not be substituted entirely for height.
