I think that can be interesting think in a evolution of the SA's in some senses.
I will suggest the idea to have the option to train a 2nd complementary SA in the players that have 1 learned, and this would be related to the spectacle-magic that for example players like Ronaldinho gave to the football.
So this SA added would create or unlock special movements, or situations that now are not in the game.
I think that there's a lack of feeling of magic and emotion in the game in the comments and this can be solved adding something to give this point of magic to some players and just changing a little bit the comments for these players when the chance to do something great comes.
