I've trained "playmaker" SA sometimes and bought some player with "playmaker" SA, too. All seem good players (young, max quality). And here's my experiences:
- They were given many cards
- They took average points after matchs (about 6,7)
- Having "playmaker" SA doesn't mean having more assist. In fact they don't have many assists, and don't score many goals (always be the worst in my squad)
- There're some MC play so well, and after I trained "playmaker" SA, they play worse than before
