If it's tough being under Rodolfo's pressure in BJJ (without punches), imagine how it'd be gettin hit in the face... DAMNNNNN
Rodolfo vai te pegar!!!
I think this IS the biggest problem with bjj gys... they rather hit over keep the pressure and end up lossing position.
I think you can go both ways, neither is wrong, but one is better suited to style.
For example.... Demian maia, he rarely punches from hg, ONLY when its necesary. Why? well he rathers move to mount, than staying in HG.
Then you have other guys that like to strike a lot from hg, soft their opponent down and look to mount or even sub from hg, like jacare.
and then you have the guys who are extremely good grapplers, move to hg or side control, and all of the sudden feel the need to start punching like juggernuts, some do have success but some, hell most, end up lossing the position, why? if you are punching you are exposing the far side underhook, people escape this way all the time.
but neither is better, it depends what your goal is and how good you are at doing somethings.
what I hate to see is people not being sure of what to do, which normally means people lossing position.
So which one is the better way to do? well IMHO, I believe maia has developed the best top game in the history of the sport, if he could somehow add some devastating GnP from mount, he would be unstoppable.
bottom line, if rodolfo get into the this is mma mindset and starts punching people form the sake of punching, its very hard to keep the insane pressure he brings in grappling...
