I find it a good idea to get tall 18 year guy with outside skills and train him for PF. This way you're getting outside skills for almost free, because he's counted for SG when sold, and costs less than he should because he's so tall and there is no point to train him further as SG.
So, I bought one 213 cm tall guy for 38k 10 days ago. He was a shooting guard then, with DMI at 10k. Look at him now: he jumped 2 popups at once (training - IS, 5 players), turned SF, and his DMI is now quite decent to give him secondary role as PF in a serious game. I bet he will easily have 7-8 more popups till the end of this season (IS, RB and ID), and he will turn into very promising PF trainee.
