Nothing. So why is it on SyFy? I can't even imagine a reason that wouldn't insult wrestling fans, so I won't speculate beyond saying $$$.
The least they could do is add some special effects. Throw in a vampire, a witch, and an alien.
They could do secluded matches, for the safety of the audience, where super powers could be used and the lives (or even souls) of the competitors could be at stake! Guest stars from various shows could show up from time to time, tech from Eureka could be employed. A wrestler could be posessed by a demon and the Ghost Hunters could show up and exorcise it!
Bottom line, if it's on SyFy it should have content related to science fiction and/or fantasy.
