I remember seeing RealProWrestling a few years back in syndication. I thought it had good potential, but maybe it didn't promote itself well enough (?). Of course you're going to be competing with all sorts of other sports during the spring, but a little more refined marketing might have helped. Then again I don't know how much funds and resources they had for that.
Another thing that might have helped was "image." When I saw RealProWrestling, the guys wore nothing but shorts and wrestling shoes. (I know this was the way it was done way back.) Perhaps they should've been allowed to wear wrestling singlets, too. I think some people still get repulsed if they were to watch two sweaty, bare-chested guys grapple each other.
