There was quite an uproar on the Tommy T. threads concerning unbending the right wrist. I think Mr. K used the term "unstressed" to describe the right wrist. There is a great post by Dr. Hit Nasty in the Hitters Section about PP1 driving and PP3 accepting lag. So basically lag is not tightly holding the right wrist bent.
So does the right wrist kind of react like the bristles of a paint brush lagging behind the handle being driven by the forearm? The brush is "unstressed" so I guess the unstressed wrist is bent as a result of driving against the inertia of the clubhead?
