Another thought on this, I think you're overstating something that is probably closer to the truth, and that is there's likely not as much difference between a kid ranked #90 and one ranked #130, while there's a much greater chance that there's a big difference between a kid ranked #10 and one ranked #50. But your odds of landing a good player are higher if you sign a 5* vs a 4*. And same for 4* vs 3*. After that, it probably doesn't matter as much, but now you're down in the 120+ rankings, and hopefully UI doesn't have too many guys in that range.
Yeah agree with all this, I oversimplified it.
