Sure, some of ECW's best talents were signed. That makes sense. I mean, while Extreme Championship Wrestling may not have always been the benchmark standard for popular wrestling, their best has always been better than the WWF's and WCW's worst. So some of their top guys are surely going to be swept up to the big leagues. I think, though, that they may be earning their jobs at someone else's expense.
Wrestling is a competitive business.
Politics aside, you can often steal someone's job by outperforming them. Bigger draws will earn better jobs and bigger paychecks. And when there aren't enough jobs to go around, they'll be the last to go. I honestly hope that everyone from ECW finds gainful employment after the fact, ideally with a guaranteed contract in a big federation. But that's just not going to happen.
