So, I tried grappling against multiple opponents on concrete. Here’s how it turned out.
First off, the concrete sucked. I took 95% of the damage I took from the ground. The rest was knuckle damage. I got skin abrasions up and down the side of my body I posted on for the “submissions”. This was the equivalent of a small beating.
Regarding submissions, unless they’re catastrophic, they don’t end fights. Just don’t and I think proper training should differentiate between typically catastrophic subs and less catastrophic subs. I believe adrenaline allows opponents to shrug off the damage til the next day.
Now, that being said, spider guard claps cheeks. I took no punch damage. The multiple opponents were an issue, but the jiujitsu bought time for my boys to pull up. I prefer spider guard with leg locks for incoming attackers. You’ll take no punch damage and stop the boot party. Back to the concrete is actually solid. No one is behind you.
Sweeping I found difficult due to the close quarters and lack of space. I fixed this by asking for someone else to hit the guy, which he did. This made sweeping easier.
