1392477 I am in your boat with size and "beef" and this is definitely a plus and minus for us, of course the strenght differential is great in fights and practice but more importantly I learned from my instructor to use my larger than normal delts as a submission especially in fights. When you are more muscular than your opponent you can tap people by smothering their face and nose with your delts/ and or sweaty bis. Theres nothing worst than being gassed and getting a moutful of some big bastards delts when hes in your half guard. When tired shoulder pressure is essential, I use it all the time but in later rounds pressure can mimick submissions, when your opponent is breathing heavy by covering their mouth and nose with your bis, delts, or rash guard makes them feel smothered, and this can end a fight. So I totally understand where you coming from when you talk about being larger. When sparring, fighting, or grappling smaller quicker guys I am with you I try to use more skill especially is practice.Practice in my opinion is where bjj and mmabjj seperate. In bjj you practice like you compete for tournaments etc, but in mmabjj I go into practice expecting to get tapped because thats where i take my chances because again its practice. If someone one your team has to much pride to be tapped then I question there ability to get better. When we train mmabjj punches are constantly being thrown, not hard enough to hurt but theres enough on them to get your opponent to move, this is when the new guys realize whether or not mma is for them or if they want to just grapple, not that theres anything wrong with that I say in all honesty I would rather right for 15 minutes than straight grapple, 15 minutes of grappling is bruttle, I got nothing but love for straight jiu jitsu guys, my worst injuries have come more from grappling than from a fight anyday.
