Hi, I'm sorry if this has already been discussed but I haven't found anything on the subject.
Suppose, for example, that I choose Rebounding for my C/PF. Will the training affect my natural-role PFs and Cs or will it affect the players in my roster that play as PF or C?
In other words, if I have a SF that plays as a PF, or a PF that plays as a SF, which of them will be trained?
