Goldberg
This one sort of falls into the “not built in my backyard” category.
Bill Goldberg was a PHENOMENON in the wrestling world, but he was Ted Turner’s phenomenon down in WCW. I think Vince thought (rightfully so) that he had the superior black-trunked bald guy on his show.
I think Vince was mad that Bill wasn’t already exclusively on WWE TV. And I think Mr.McMahon just flat out didn’t like Goldberg. Billy G didn’t really care about the wrestling side of the business, just the money part.
In that sense maybe Vince and Goldie Brawn should have found common ground. Because as much as VKM hated Bill Goldberg, he LOVED making money, and Goldberg equalled BIG money.
So he bit the bullet and signed him. While his run in the WWE may have fizzled out unspectacularly, Goldberg is world famous to this day.
