No, this is happening because quality don't mean anything, is just a level in nº, and stars are just to have the referance of the distance of Quality between players, to do the simulations. A player can have more quality that a 2nd, but can be worst proggrammed by default an, thats the important here, internal proggramming of the players.
Rating doesn't matter, the important is how a player contributed to the team. So, if your GK don't recive goals and have a 5, don't worry.
If the player with highest Q. have 5-5-5-4, see what he do, because you have to decide, looking if is well proggrammed, without see the Quality.
