I would not bother bro! I trained a S.A. MC, in season 2 but the time it took me to get all the points it I was into the next level so he lost a star! he was still ok for about two seasons but from what Im led to believe a player that has a SA is only as good as the star he is so if he if you have say a MC SA 2* 25 and a MC 2*27 the player without the SA is better plus if you then go to the next level the SA will be 1* what ever and the average 2* player is better!, Save your points for the extra star bro unless you are going to throw boosters at him and power train.
