@ Cutsy
i pretty much answered your question over PA change after i said '@ Cutsy' in my previous post, once the game starts its set in stone, players like lampard will have a set PA because its obvious what type of class he is, players like Sanogo will have -9 for e. g. because the developers know that he is a hot prospect but they dont know whether he will be amazing in a few seasons or become another sherman cardenas.
i showed you the filter because you are to obsessed with PA,
actually start a new game, and dont look at PA and CA, pretend your a manager, use your scouts and look at a player your interested, use your knowledge of management simulation games to actually make a decision on when to sign him? do you think when fergie get shown a player by his chief scout he goes 'what's his CA/PA? if its not at least 190, hes not getting signed up :/'
