you're right that most people don't have the personnel... but it's strange that a defense requires a specific roster type. For example, does any team not have the personnel to run 3-2 zone???

Imagine if 1-3-1 zone was worse vs. outside offense than M2M is...
I wonder how it would change if there were two outside defense skills; one that was about turnovers (stolen passes and dribbles) and one that was about defending jump shots. If there was a case and then nobody trained the second one because it was too expensive or didn't do enough or whatever, would 3-2 be broken and would outside offenses be dramatically better?
Of course, I'm not sure that could work - as it is, there are six primary skills for guards and although some people don't like taking JR too high, pretty much all of them are useful and need to be trained. Adding a seventh would just make it that much longer to train a well-rounded guard, while big men continue to have the three skills that people train and one skill that everyone treats as the red-headed stepchild.
