i can read ;) I even understand you, but playing double team, when a star player comes in possesion is an option you choose out of a man to man defence. In a Zone it works pretty bad, there you can collapse when the ball comes to the low post maybe even only when Dwigth H. comes to the ball. But a double team he asked for, what special pressure for single player, you normally not make extra out of a Zone since the transition of defence the other had to make need to much time.
Seelenjaeger said, that you play it such a short stretch, and he mean every tactic beside man to man during a game, with few exception this is right. but i think this simplification, is quite good for the game.
but he didn't say, that double team is an extra, you combine with defence strategy.
