Thanks for the post, It really cleared some (a lot) of things :D
But something isn't "THAT" clear...
Balanced training, in my opinion, is one of the most underrated aspects of BuzzerBeater. I firmly believe that if your main skills for a player are pretty close to each other, their training will show a marked rise in efficiency. Train one skill to legendary while everything else is at strong, and you're asking for trouble.
By Main Skills, you mean for example... All perimeer skills for a guard? Or only the "main main skills"?
