5 ball potential or 5 ball skill?
I like to belive that it is of ratio(with potential).
For example there are 3-1 ball 20-2 ball 20-3 ball 3-4 ball 2-5 ball ers in your list.
But the level of uncertainty can be a 3, 20, 19, 2, 4 ------ or maybe 5, 16, 18, 9, 0
I mean it probably is randomized like that, but the uncertainty factor can give you an excellent draft, or a mediocre one. But not every NBA draft is as good as the last, so it is for he best.
