The key word is "don't know how to turn off".
From a wrestler's point of view, I love to deal with "full resisting" opponent. I will know that my opponent will resist against everything that I try to do on him. When I pull, he will pull too. When I push, he will also push.
Comparing a "full resisting" opponent with a "full yielding" opponent, the "full yielding" opponent may give me more trouble. When I pull, he will push. When I push, he will pull.
I can take advantage on both "full resisting" and "full yielding' opponent.
The most difficult opponent to deal with is those who can "vibrate his body". No matter what you do on him, his body vibration can cancel out all your force.
