There's a function, in every SA... then, depend if is well programmed... or, if another SA internally dominates, to create situations thata are more typical from another SA...

For example, not about SA's but today, I did a subs' in the match, as AMC I changed the ST that was there for another ST, and this worked in defense all match, saving me.

Talking of SA's, I had in my first seasons a good playmaker, called Edgar Davids, that scored a promide of 1 goal per match and with the same action, "suddenly shoot from far away" (it said : Davids suelta un trallazo" and then, goal in 90% chances. I think that this action is more typical of a shadow striker... but not sure, maybe too for playmakers is internally avaliable...
Then as ive said all is the same, a SA, give a advantadge in some actions, but for example is not so strange have 3 players corner specialists and see that the best man is another...
In this game, nothing is a guarantee,test is basic, and who dares sometimes, win.
