If someone bases hard then my transition is pyramid. I catch the wrist before it gets to the ground. Im always hunting a wrist on that side. Their shouldnt be a limp arm if your overhook is strong and you are elevating them. Alternatively if the hand is super heavy it means the knee might not be so I have in the past, kicked their knee on the same side as the wrist control. I have also used the sweep to get them on their side and hit vice grip to D'arce
