'Illegal because you need At least 1, but no more than 2, players on EACH outside flank. {the D(L/R), DM(L/R), M(L/R), AM(L/R) slots}
If you play an illegal formation, possession is 80%-20% in favor of your opponent.
Unless he has an illegal formation too .. then i dunno what would happen ... need to test that.
