How many times does a pro wrestler need to have what is considered a career-threatening injury before they retire? How many times can a pro wrestler not retire and possibly shorten their career by untold numbers of years. In the case of Chris Benoit, we never quite figured that out. Sadly with Daniel Bryan, we could get this answer. It's not so much the wrestling, but the style of wrestling done by Benoit and Bryan that's (potentially) at fault.
