There aren't enough example of 7'5 for comparisons to make much sense, at least as direct causes (more correlations imo)
Different body type, different background, different type of growth, some having "gigantism" condition, some never prepared their body from a young age, most didn't work on their flexibility or different aspects Wemby works on today etc
Wemby is 21 and other that a blood clot, that isn't an injury, he hasn't shown any type of physical weakness since he arrived. His rookie season Pop invented a sprained ankle to force a month of min restrictions (Wemby candidly admitted it at the end of the season) and this season he had no pain 2 days after his calf "injury".
It's as if, even unwittingly, Spurs were trying to convince Wemby he is fragile...
As for your PO reference, you can't use a player 20' all season and suddenly use him +30' during the POs
You can't dismiss the importance of the RS in a career and how frustrating it must be to be eliminated from any individual price bc you'll never play 65 games or only play 20' and can't make strong enough numbers.
You can't just think in your interest, you have to put yourself in the player's shoes because he won't perform at his best if he's not happy.
