short stretches
This is the key. m2m, even 3-2 may work the hole game. but 2-3 I've only seen it work when I play basket with friends, who are no Steve Kerr from the three point line and we always get the edge on rebs. ;)
a good 2-3 could also protect the perimeter good enough, i believe syracuse is a pretty good example how it could be, that is maybe rare and extrem but ain't that all strategies here? I mean, motion offense looks for a layup after cut first(if i remember right) and even when it end up in many long distance shot it is far more balanced ... And in my eyes, this should coun't for all tactics here(guards punishing help D in the corner with inside tactics). But it is also good, since it makes strategy possible, or at least better visible here ;)
maybe another example of a working 2-3:
