Good posting Scoop,
Wallet done quite well with his long kicking fallback theory on playing the zone. There's plenty to work with there.
Thinking about it, they have 14 or so players covering the ground evenly. Whats to stop the majority of your players starting out at the defensive 60m mark at CHB. They all move to the top of the square diagonally on ONE side, You are going to massively outnumber the hawks at the ball. The big men either mark it pass it on or knock down to the plethora of players in numbers who are breaking past. Keep 3 or so at CHF as leading options as well.
Sure its high risk & there's a chance of a turnover to the Hawks who are all free in the attacking 50m for an easy goal, but with extra numbers at the designated fall you'll win more than you lose & there's be an open forward 50 to attack to as well.
What you are doing is making a rendering a number of Hawks players in the zone useless, leysy believes this "zone" will get blown away by some sides as the year goes on.
