It is an epidemic in High School, College, and Pros, and the reason you don't see it in the NBA, is because it has been a full decade-plus now since the League raided NCAA ball..and now thanks to ESPN's DunkFest HighLites..all games on all levels are whored out.
The reason something like Dr.J or Michael Jordon dunking from the FT line isn't exciting, is because everynight..is Harlem Globetrotter Night at your local arena..it's played out ad-nauseum.
And that Washington General Matador Defense is on display at almost all arenas across America..HS, College, and Pro.
I wonder if guys like Walton, Bird, Frazier,etc..really watch much NBA ball today outside of being paid to do so?
Ironic isn't it Chuck, that the same allowance for walking started for MJ and Ewing,etc..to create skywalking to the rim, is now the exact reason so many over the age of 30(that know better)..do not watch NBA ball except for the Playoffs.
