It’s hard for an opponent to attack you from if you don’t allow his to make effective connections to your legs and arms: Effective attacks in Jiu jitsu are predicated upon effective that form connection between you and an opponent. You can use that connection to and attack. If you can’t and connect – you can’t attack. Now position has two major forms of grip. The is the more obvious one – your hands to your opponents body. The second is your to your opponents body (usually the legs). Your feet do almost as much grilling as your hands in Jiu jitsu. When passing, if you can shut down your opponents ability to grip you with his feet, then you will have gone a long way towards shutting down his offense, and with his shut down, now you can on the fun stuff – passing his guard – without the distraction of being attacked as you try to pass. Seek to control his feet and prevent them making effective connections to your legs – your passing game will thank you
