#3 Braun Strowman vs Brock Lesnar
As with Samoa Joe, Brock Strowman has already happened. However, most people have faced each other in WWE currently. And given how dominant Strowman has been and how popular he has become, it only seems fair that he is the man to beat Brock and become the new beast of WWE.
Strowman is probably the most over man in WWE today. He is constantly doing new and exciting things that make fans love him more and more. The latest of which involved Strowman power slamming Kane through the ring on this past RAW.
This is just one of many things that have made Strowman so popular in WWE and if WWE book him right, he could be a huge star for years to come. One way of doing that is by having him and Brock Lesnar main event mania, have them absolutely destroy each other followed by Strowman's win. People would be very invested in the match as there’s nothing like watching two giant monsters destroy each other. Plus, if Strowman wins fans would actually cheer as they love him.
