lol "movement"...hmm let me think...right, I'm pretty sure your opponent plays "Motion", since the word "motion" could be described as "movement" in other context.
If he plays motion, generally speaking, his outside offense will be better, so I'd say use 3-2 zone, if your Man to Man rating in outside defense cannot stop their outside offense. Motion is mid-range - outside focused, so SF does play an important role there (although I think SF is important in all the offense anyways). I'd go with 3-2 zone, if your opponent's inside and rebounding aren't that good.
