I know that players can only improve BPOS at a position in a game if they play that position and only that position in said game. If you work around that problem by playing a player at one position in league games and the other in friendlies, for example, is there any other downside to a two position player?

I have not noticed any difference between league and friendly games regarding BPOS. They all seem to take 10 games to increase .5*.
