Hi HerbM,
You are absolutely right.There are alot of exact matches, because boxing has evolved from free fight and when you fight without big handgloves you must use robuster parts of your body(forearms and sholders) and you must be much more elusive(not like the new UFC guys eating punches like candys)... I think there is no difference between Stone wall and philly shell too. Only in the stone wall Champ Thomas has forgoten some very important things like rythm...
