Yes, that is true. After listening to all those people complain about 2-3 allowing driving guards and open 3s, I analyzed many games and comparing 2-3 to man to man, the number of drives by the guards were quite close, therefore shows that almost everyone who claims 2-3 is crap is talking crap. However, it does leave your team vulnerable to a lot of 3s...
I don't really get where he says Base Offense is the strongest offense. It's clear in the GE that the best offense is solely dependent on your personnel. And not by being flawed either.
