#3. Having Brock Lesnar retain the Universal Championship
We hate to break this to you, but Brock Lesnar walking out with the Universal Championship is far more likely than you think. Sure, Seth Rollins deserves to be a World Champion after 3 years of not being one and sure, he does deserve to be the top guy.
However, Roman Reigns' return seemingly ensured that The Kingslayer won't become The Beastslayer anytime soon. They haven't really built or made it seem like Rollins is going to win, despite looking good at the go-home show.
And with two other big babyfaces potentially winning, they probably don't want to make it seem too predictable, though Rollins winning would absolutely be the right decision.
However, more likely than not, we're going to see Lesnar retain after a few F-5s, and the match probably won't be much longer than 8-10 minutes or so. After that, WWE will probably run back Reigns vs Lesnar for the 5th time or so.
