Without that fulcrum, there is no Princeton. One caveat, Sidney Lowe seems to have modified what he inherited into a very inventive derivative of the Princeton. From what I could tell, entry passes come primarily from the side of the court to the hub in the low post. The dives to the basket come from the off guard position on the other side of the court, or something like it.
I do not see JTIII abandoning the Princeton or going Lowe. I do think that your perspective about the efficacy of doing something different to be intriguing; if you've called this one, Maipei, you deserve a special spot on this board. Jumbo who?
