I pulled a decent 3-2 rating today which was inline with what I was hoping for... so contrary to my original post this is the first time I am coming round to the idea they are ok.. but my players are probably still short of JBMs when it comes to OD so I am bemused at his team ratings earlier today.
i played 3-2 on saturday (at home), pulling a proficient (low) with defensively inferior sg's and sf's. so unless home court bumps up the outside d by three whole levels, the outside d level of a 3-2 is more or less random.
