Goldberg should take a good look at how Brock Lesnar conducts his business. Whether you hate or love Brock, he knows how to make $$ without letting his pride or ego get in the way of a moment. Brock comes back and gets paid a huge salary for a few select dates and and jobs, he doesnt always win, hell he lost his first match back, but he got paid $$$$$ for it. And people LOVED it. What could Goldberg bring back? Some nostalgia, sure, but other than that, what?
I thought Goldberg was awesome, I thought the character was great, a pinnacle of wrestling during his time, but if he were to come back now and destroy everyone and win all the titles, it would prove how much of a work WWE really is, more so than having a UFC champion come in, go to war and lose to a "fake" athlete like John Cena or Trips right away. Plus he has to be going on like what, 50 now? He may be in great shape, but he has no wrestling sense other than knowing how to beat a guy.
I know some people might disagree with me and comparing him to Brock Lesnar, but Lesnar has the business sense to know how to make the money for himself and the business, Goldberg just wants money for himself. He would probably expect a seven figure salary for two months work. Na uh.
