Sabu jobbed to Samoa Joe becuase he was going to jump ship to WWE. That was no big secret to anyone.
I do like the idea of Free Agents in wrestling, because you could see people jump from fed to fed, but at the same time... It would never work because once you get a story line going with one person, they are gone working for some other promotion.
The next big thing in wrestling is not going to be this 'free agent' idea.
In my opinion with ECW coming back, and supposedly ROH going to PPV this summer/year (can't remember which one) will shake things up a bit and possibly(hopefully) make wrestling a better business all around.
