OK, what I've wondered is this:
What's the difference between playing someone onto their right/left foot and playing them onto their weaker foot? It gives you those three options, and I don't understand why.
Does setting it to "weaker foot" rely on the players themselves to work out which one is weaker?
That's what I've always assumed. Surely that's the only reasonable explanation. Or unless it's to catch lazy people out who always go for 'weaker foot' without checking if the player is two-footed or not.
