If they'd enforce some sort of out-of-bounds rule, or even the rule that Spider cited, I'd be willing to watch folkstyle on youtube again. Right now the out-of-bounds crap drives me crazy. It works but it's annoying as hell.
On a slightly different note, I once heard Matt Gentry say that folkstyle wrestlers nowadays are using "folkstyle-only" defensive techniques (I guess playing the edge would fit into that category) instead of old fashioned defence lie a good sprawl. This then hurts them when trying to wrestle freestyle.
I think it is an OK strategy to go to if the situation calls for it.
I don't think it should be a main strategy that is used every match.
Kind of like stalling. If you are up a point in a big match with time running out, the put on the roller skates, otherwise wreste aggressively.
I was at a coaches clinic when the lecturer-some old guy from OK STATE-I was 23 at the time-actually bragged about how he was the ONE who came up with using the edge -itwas a 2 day clinic -I left after 2 hours . It was suposed to have been on takedowns and set-ups -didn't know t was going to be an Arthur Murray studio .
To me it is mat awareness. Wrestling towards the edge is smart wrestling. gives you the oportunity to score using the whole mat and defend if you get caught in a bad situation.
Boxers use the ropes in the same way, Football uses the sidelines. Like said in other post win win win using anyway legal and the edge is legal.
I used to do it. Not proud of it. But was really good at it.
