Dont bring in player density! The ball movement is far quicker and the principle is the same. A quick pass over 50m means an opposition player could make up atleast 5 meters of ground. A quick pass in bball might only allow a defender to extend an arm.
Yes but if you're kicking it 50m it usually means there isn't 36 players in a third of the field you're kicking into. The reason I said 50m kickers is because you have the current massive clusters around the ball and to the likely area of next kick. If you have a player that can run with it for 10m and kick it 50m to a player that will likely mark it even with pressure then you've just blown away any zone that can be invented. ANY ZONE.
Unlike basketball a lot of time in football is spent in the middle of the ground basically making player density in worst case about 220 square meters. No zone can properly cover that density if you have players with good quick kicks.
Zone only works in football if everyone is on same page. Like in Bball if you have 1 weak link you will get exposed.
I think you mean the zone works BETTER when you have team cohesion in regards to running it, but the same can be said with any setup.
Go over nearly any game these days and count how many goals are scored with players running in unopposed into the goal square or bouncing it through. Just by ALWAYS having one player back near goal regardless of what's going on you will save 2 or 3 goals per game that happen like that.
Like i said the whole structures thing is really in its infancy and the key over the next 10+ years will be football smarts, something i think Dockers have identified already.
The thing is, even in basketball, good man on man still defeats every zone defense. The only thing zone defense is good at doing is covering up holes of ordinary players, if you have the better players you will win with man on man. Of course you can't do man on man easily if the other team is running a zone. However if you have smart defenders and keep them in their back half and make sure they pick up appropriate players who run forward regardless if they are their "specific player" it should keep the defense strong.
