1st one. I'm damn sure. Confirmed by GM-Jason.
Does that mean that the C actually defends the wings at 0 degrees? So he would need some OD?--> better swap PF and C in defense?
i know it played with guard below the basket cause they are fast, maybe you could ask it in the Ask a bb thread in the global.(or maybe the assigment the C have there, if he don't protect the corners here the c is placed well).
I am not sure, if you mean that me as a GM should have more insight in game mechanics, but the BB policy was always more about let the users explore.
