The biggest thing to keep in mind is that the live match does not represent what happens on the field. Yes AML/R will be more aggressive than ML/R as far as attack and counter attacks go. You cant expect a player to stay 100% of the time in the same position so it is natural for them to move all over. As far as what difference does it make if you put them in more forward position or back ,we still dont know yet and it has not been answered.
