you don't have to over commit, attack can be organised, you
don't do it brainlessly like what you define as schoolboy football.
A counter attacking team usually uses a solitary striker which
should be marked out by your (1 attacker - 2 defender)
combination.
A counterattack happens when teams over commit and when your
players don't run back to defend.. When you attack and cover, you
won't over commit.
just keep prodding, keeping possession.
the defending game can only work with teams who can finish with the
tiny chances you will get in each game. if you don't have a good
finisher, then you had better attack.
i'm not saying attack from a tactical point of view yet, its just
pure common sense.
