Very interesting post..
if I understood everything correctly, from this point of wiev the 2-3 zone shouldn't be broken (or at least should be better than 1-1 for inside offence), because it increases the ID and decreases the OD.. So, the guards should take open layups because the od rating is lower, but should miss because of high ID rating.. How would you explain this? Because from my experience, the driving layups are often choice against 2-3..
