Holding on to grips too long is one of the biggest mistakes in Guard Retention I see people make when playing guard at all levels. To control someone you need grips but at the same time when someone is passing you, you need to know when yo let go of the grips and focus on framing and protecting your elbow knee space. This skill set of finding the time to defend and then re entangle your opponent is a critical transition skill set that is often overlooked.
