A former professional Football player, Wilbur Snyder entered the pro wrestling ranks and made a mark for himself almost immediately.  Snyder competed primarily in the American Mid West and would eventually buy into the Indianapolis based WWA promotion.  While there, he was one of the top draws and constantly was holding championships there.  Although he was a former gridiron great, Snyder was a technical marvel and is largely credited with inventing the abdominal stretch.  Snyder never really competed under the WWE banner, but every now and then you will hear a commentator refer to the late Snyder when a grappler applies the abdominal stretch.  Sounds like an impact to us.
