There are multiple forum topics I have seen that have discussed zone. the following topic has a really good but complicated post from gillespie on zone equations.

i guess it was too complicated - the old forum wisdom is that the pg/sg are averaged, etc, but really all 5 players are averaged on every shot. its that the pg/sg etc (in the 2-3) run off the same equation. its not terribly bad to think of them as averaged, because we really don't know if all 5 players are weighted equally, when averaged together. my guess is that in general, guards do count more in defending a 3 than the center, even if it is only a product of their higher per defense ratings.
anyway, thinking of zone allowing you to average in a bad defender, and not be exploited like man, is good, thats how you should think of it. just don't think of it so strictly like its certain pairs of players being averaged. think of it like, the entire team contributes to defending every shot, which lets you hide a bad defender somewhere, unlike man.
