thank you both for your answer
i have no idea which is the best way to use this zone that's why i asked because i tried it in one game and i saw a really big improvement in the outside defense i will continue try this defende at the private league and if i see it works better for my team i will use it in the league games. the most of the skills my players have it the only skill that i need is OD at my PF is not so high inept
