I wouldn't say I agree with Prashant up here. It's not always wise to play your offense according to your opponents worst defense. It is a truism if your team is really balanced and can play inside or outside with little loss.
I would never play outside offense if I only have defensive players in my guards a sf positions and have 2 great PF/Cs. There are teams playing like this with nice sucess, and they only play inside offensive tactics.
You always have to weight both sides of the equation and remember that this game is not only about ratings and a lot about matchups.
