Sure, Goldberg VS Brock Lesnar at WrestleMania doesn't really need the Universal Title to sell as they're two of the company's biggest stars. But, neither does Chris Jericho VS Kevin Owens. A standalone bout with its own story unfolding. Plus, they're gonna have the United States Title on the line anyways. A "winner takes all" match would be pointless here as well. In fact, the story with Jericho and Owens is much greater than that of Goldberg and Lesnar. That being said, Goldberg VS Brock Lesnar with the Universal Championship on the line is, without a doubt, the most sensible decision in this case no matter what way you look at it. Brock and Goldberg need something they're fighting for as they've already competed before, or any sort of stipulation would have done the trick. Jericho VS Owens on the other hand is a fresh contest with a tremendous story behind it, and doesn't need the main title involved at all.
