Because Goldberg is one of the best people on the mic, he was one of the most technical, and one of the best sellers. His diverse moveset set him far apart from the likes of Jericho, Benoit, Sting, Scott Hall, or just anybody in WCW at the time, and possibly even WWF. He always trained and had a passion for wrestling, one that can't be measured. His mic skills were tremendous. Everytime he spoke he just spoke from the heart, you could believe every single thing he said. He spoke so much quotable stuff, that it's just to hard to remember most of it, the only quote that pops into my head right now is, "you're next!"
Goldberg was one of those people who could bump and sell like a pro too. Everytime he would get hit, you would jump up because he just sold it like a 5 star fisherman catching a catfish. One of the things people seem to forget is how many people he put over. HHH and Nash. These two really needed the push in their career. Nash was a former world champion, but he needed this reign and to end the streak because Goldberg offered it to him. HHH needed it as well to start his first and only world championship reign.
As you see, Goldberg was a tremendous man, a legend, some might even call him God. He was generous, technical, vocal, and of course, one who put people over. I'm glad his legacy will never be ruined by TFA, because Goldberg's talent would be wasted there. I hope you understand the man they call Goldberg now.
