Hello Gang! A question for the grappling specialists on here. Recently I was around some wrestlers and BJJ practitioners who were discussing escaping from the mount (top saddle) position. Both sides showed good workable stuff, so I'm not starting a "my art is better than yours" argument. I'm just questioning some specifics and looking for answers from the specialists here. The BJJ people recommended trapping the foot with yours (if I'm explaining it right) when you arch, and roll them off. The wrestlers recommended not to do so and that you lay your leg flat so as to prevent a post out with the leg of the attacker. In all of your practice of BJJ, has anyone posted their leg, preventing the roll or does trapping up their foot with yours work fine? I ask because while demonstrating each showed that their way worked and there was no flaws.
