1a) The Principal of Verticality has been in the NFHS and NCAA Men's Rules Committees nomenclature since at least the 1950s and the NBC The predecessor of the NFHS and NCAA Men's Rules Committees.).

1b) The Principal of Verticality has also been a part of the FIBA nomenclature but not part of the NAGWS (AIAW: women's college). It became a part of the NCAA Women's Rules Committee when the NCAA supplanted the AIAW and merged various parts of the NAGWS Rules into the NCAA Women's Rules.

1c) The Cylinder of Verticality is not a new concept. It has been part of the FIBA nomenclature since at least the 1980s.

1d) Despite the NCAA Men's and Women's recent addition of Cylinder of Verticality to its nomenclature, the Principal of Verticality has always (with apologies to the late J. Dallas Shirley) implied the Cylinder of Verticality. The Principal of Verticality cannot exist without the Cylinder of Verticality.


2a) I have a Hand Check Foul by W3 on R22 at 0:02.5 on the Game Clock, which would end this discussion now but since the Common Foul (CF) was not called let us press on.

2b) From 0:02.5 on W3 has breached R22's Cylinder of Verticality and at this point W3 is responsible for any contact between W3 and R22. And at 0:01.8 W3 and R22 bump heads. This is a CF by W3.
