I have to say that this current match is very difficult for you to win because :
1)You have 2 basic players that are injured
2)Your players game shape are low instead of opponent
3)You play away
So he has advantage to win this match..
As for the zone 2-3 is suggested if the opponent will play look inside or low post
Just see BB3 final season 25
(65653784)...They use it rarely but it works
If you want to not risk play man2man
