The problem with that defense is it only really works against patient or against teams with a dominate outside scorer playing in an outside based offense. I'm guessing that he played patient sometime this season but if he switches to an inside defense, it's going to backfire quickly. And it actually did backfire because you gave up a ton of points. You just outscored him is all.
You definitely didn't win because of your tactics, you won in spite of your tactics my friend.
