But it's a grappling that is alive and flowing by utilizing what we refer to as CONTACT CONTROL, and not actual dead hand fully committed grappling.
What do you mean by "dead hand" in this context? Is it like a "death grip", perhaps?

I read the HFY108 thread you quoted, there was some good though, not revolutionary or revelatory, thoughts presented there, but it didn't explain the distinction you make here.

I wouldn't describe wrestlers as necessarily having "dead hands", myself. And I've met no decent ones that aren't VERY "alive and flowing".
