williepep - Anyone thst paid attention to Mario Sperry' s VHS instructional tapes knows that Conor should thank the Zen Machine Mario Sperry.
We have been practicing those shoulders since the mid 90s thanks to Mario passing them along
Many old school boxers have used them when needed as well
Bing! :-)
I've been teaching it since Josh Barnett used in that SuperBrawl tournament in the 90s (Sperry tapes were after). But I taught it wrong - for impact pop point of shoulder forward. To set up a punch, use hips like Conor did. I will be explaining my error in Wednesdays MMA class.
