Yes so even in the NBBA, in fact in the whole game there aren't good enough players to make the 2/3 zone work. So it isn't broken, just no-one anywhere has good enough players to make it work. Please explain how this isn't broken?
A man to man works with any player. You can run a 3-2 with guys with respectable OD and it does what it is supposed to and cuts down outside shots. A 1-3-1 needs a good center and then it does what it is supposed to. FCP does get a lot of steals but it does give up a probably unreasonable number of offensive rebounds but it doesn't need any magic players, just better defenders than the opponent has handlers and pasers. 2/3 needs players that even you admit don't exist in the BB-Verse to work. Broken!
Have the BBs even given any hints on what that type of team/player is?
7 in OD for an inside player of +100k salary is not high, is next to that, try to train a 213 tall in OD much time ...
