This build is impossible for a couple of reasons. First of all, it is impossible to ever have a build with 20DR and only 13HA. Even if you started with 1 HA (the lowest possible) and 7 DR (the highest possible) there's still only a difference of 6. And due to a combination of elastic effect and height, handling will only close the gap. So HA would be at least 15, which would be a fairly substantial cap hit.
Second, that build right there is almost 150 skill points. I don't think there's been a player with even 140, even players with awesome starting skills and who have had level 7 trainers their whole lives.
Third, 20 IS and 20 OD on the same player is pretty much impossible. There are fairly severe penalties training OD on tall players, and IS and SB on short players.
Fourth, you're probably not going to get all inside skills 13 or better and still have only 3 rebounding with elastic effect. Of course, this is a fairly minor detail.
So this build is so far out of the realm of possibility that you'd never even get close, cap concerns aside. But a player like this would definitely be pretty killer.
