#3 Goldberg is very expensive
As a little kid, I used to watch World Championship Wrestling on a regular basis, especially to see my idol Sting in action, not knowing about any ratings 'wars', but just enjoying the product for what it was. And then, this larger-than-life athlete called Goldberg came along and just changed everything for the company.
It is crazy to think that so many years later, Goldberg is still a draw, at the top of his game. But he is still a very expensive proposition for the company as one would assume from a performer of his stature.
In case you need any further clarification on this matter, just click here and check out what Sportskeeda's resident wrestling expert Tom Colohue has to say on the whole matter. WWE cannot afford to keep the title on Goldberg, because, well they cannot afford him quite literally.
There were no further appearances planned for Goldberg after this one, and one only assumes that Braun Strowman will hold the Universal Championship for a long time.
