I do not agree with Manon this time. I would definitely play 2-3 zone although some say it sux. Galatasaray doesn't have anything outside, just that inside play. With 2-3 you can crowd the post and help defend against his C beast. Some will say you'll weaken your outside def, but your opp doesn't have anyone capable of hitting 3s.
Take my last game as an example, but decide on your own what you'd like to believe about 2-3 zone :) I played TIE because I was certain I'd lose. Strangely, I won by 18...
