Always thought part of the Goldberg fizzle was the way they booked him to lose.
The loss shouldn't have done squat to Goldberg. He'd already lost in his career. It wasn't like he was still undefeated from WCW and then got jobbed in WWE.
Goldberg failed because he was below average at absolutely EVERYTHING other than intensity.
He worked in WCW because they booked him to be a wrecking machine and didn't have him wrestle long matches. And he was something different from the endless nWo stuff.
By the time he got to WWE people were well aware that he was average, on his best day, in the ring, and he was terrible on the mic. WWE was full of people who were great on the mic and great in the ring. He simply didn't stack up.
It also didn't help that his first feud in the WWE was with the Rock who was, by far, the best in the world on the mic at the time. Goldberg never stood a chance of looking good or doing good in the WWE.
