#3 Gives Brock a credible opponent before Wrestlemania

Whether we agree with it or not, the main event of Wrestlemania 34 will be Roman Reigns vs. Brock Lesnar for the Universal Championship. Vince McMahon is hell-bent on getting the Samoan over to the wider public and a clean win over Brock Lesnar is one of, if not the best way to do so. In order to keep building Brock Lesnar up as the monster he needs to be before Wrestlemania, he needs a credible opponent to beat at the Rumble to give him more legitimacy.
On the same night, Roman Reigns wins the Rumble match, Brock Lesnar and Kane need to put on a beastly physical encounter. An encounter so physical that it makes us look at the Beast in an even more awe-inspiring manner.
