If by century you mean until his 20th birthday, then you are right. Considering that his height would slow down his OD training, but that its level ralative to his other skills would increase it, let's say he gives him 24 weeks of single position guard training. On his 20th birthday he would be
Hüppevise: nigel (3) Viske raadius: hea (7)
Väline kaitse: hale (10-12) Pallikäsitsus: hea (11)
Üks-ühele: hea (11) Söötmine: hea (7)
Lähivise: väga hea (8) Kaitse alas: väga hea (12)
Lauavõitlus: väga hea ↑ (8) Viske blokeerimine: väga hea (8)
Vastupidavus: nigel (3) Vabavise: nõrk (4)
Kogemus: olematu (1)
From 20-22 work him on PA, OD, and JS or 1-on1 in a three skill rotation, and that guy is a great player on his 22nd birthday.
