To develop the best position player possible--which is more important:

--assigning position based on skill scores;
Or
--assigning player to his natural position role??

Seconded. It takes my players 11 games to improve 1/2 a point in their BPOS, so if you play a player all season (league, cup, and friendlies), you should expect ~1.5 star gain to BPOS.
