Although Wilson's battle often has been a lonely one, he says Benoit's death might reinvigorate the cause.

A union could be a useful tool for cleaning up the sport. It might lead to a pension plan, improved benefits, more stringent health and safety guidelines and a revamped pay structure that would allow wrestlers to spend more time at home without risking a pay cut.

Now, most top wrestlers get a guaranteed salary, but the bulk of their income is based on how often they compete. That leads some to feel they must get in the ring while injured, often with the aid of painkillers and other numbing chemicals.

And much like rock stars, plenty of wrestlers have fallen victim to excessive partying, alcohol and drug dependency, and marital problems during grueling stints on the road.

"My longest run was 79 days in a row without a day off," said Joe Laurinaitis, the wrestler known as Road Warrior Animal and father of Ohio State football star James Laurinaitis. "It's not as bad now. They've got good guys running the WWE. Still, we need to take a look at it when things like this (the Benoit murder-suicide) are happening. Guys are still overworked."

That's why Wilson's calling for Congress to hold hearings on the wrestling industry, much like it investigated doping in professional sports and just this past week heard from ex-NFL players who believe they're being shortchanged on their pensions.

"In those other sports, they aren't dropping like flies like they are in the wrestling business," Wilson said. "Now is the time to push for legislation nationally."

He's already spoken with U.S. Sen. Johnny Isakson (R-Ga.), who instructed his staff to begin gathering information on the issue to determine if a hearing before the Health Committee might be warranted.

Isakson said his main concern is steroid abuse.

"I'm not going to start speculating on federal regulation of wrestling," he said. "The issue is anabolic steroids, which are a significant problem and are known to cause significant difficulties. It's a health issue that's appropriate for us to discuss, regardless of the profession."
