You could provide 2 examples of skills of the same potential where both players are capped. There is no way to know who the player is so you are not breaching anyone's confidence or trust.
I am sure you would need more than 2 examples (I did). Because, for example, on a guard: you may wonder if 3 levels of rebounding is the difference. Or on a C: you may wonder if 6 levels of handling was the difference. I think, it is only when you start to see all the data that you start to become more convinced.
