The point is that you have to make choices on which stats you want to have high.
You can't have all very high.
But actually, you don't need them to be very high to beat your opponent.
A good forehand & form (about 80%), with a correct backhand (60%) will be enough to develop a defender or puncher tactic, even if all your other stats are pretty low.
So model your player according your own way to play !
