#2. Goldberg

Believe it or not, Goldberg is now in one of the worst situations of his entire career. In fact, between being the guy that ended The Fiend's streak at Super ShowDown, and losing out on all the momentum that had been built-up to WrestleMania with Roman Reigns, the former WCW Superstar is very much a paper champion at this point.
Think about it this way. Now, on top of the resentment that fans already feel towards him for ending the streak, the company has to find a way to build up a feud for him within two weeks. That's not going to be an easy thing to accomplish by any stretch of the imagination and could seriously damage the reputation of the Universal title in the process.

In the end, Goldberg isn't popular with the WWE Universe already and the fact that the company has to go back to the drawing board is only going to worsen that. Of course, that could end up working in the company's favor if they milk it in the right way, but it's still a long shot at this point.
