I remember either reading or watching something that said on average, NBA players have much larger wingspan-to-height ratios than the average human. So if Withey's wingspan is only 3" larger than his height, he might be below average. Just checking a couple to compare, Anthony Davis is 6'10 and has a 7'4 wingspan, Durant is 6'9/7'5, Dwight Howard is 6'9/7'4 and LeBron 6'8/7'0. Well, yes, but that's Allen's Rule.
