As regards the zone defense vs. an outside tactics - so as not to be angry, you should keep in mind how it is in the real basketball.
Zone defense in basketball is not particularly played against teams with good shooting skills as zones (all of them) are easy to beat from the outside. Zone defense was "designed" in order to force the other team to shoot, because when there are 5 players standing right "under" the basket, there is not much space for guards to drive or to big guys to post up as they can be double/triple-teamed easily without much chance to pass the ball. Instead, when attacking against the zone, players should be cutting without the ball and passing it as fast as possible in order to create an open shot - against 3-2 zone it is usually in the corner, against 2-3 it could be in the middle or from deep wing, if you know what I mean.
Of course, I dont know if the new GE is designed this way (and I dont say it is) but it could be; and even if it is not, this could be a hint when you are making a decision whether to play 3-2 (1-3-1) zone or MtM against outside focused team.
