#3 Should - Brock Lesnar could pass the torch at WWE WrestleMania 37
As mentioned earlier, Brock Lesnar is not just one of the biggest names in WWE but is well known across the world of combat sports. This has not only helped benefit the company but many other Superstars, too.
Seth Rollins and Drew McIntyre benefited from facing Lesnar during the build-up to WrestleMania 35 and 36. Both men became crowd-favorites during the time and went on to defeat The Beast at The Show of Shows.
McIntyre is still riding on his victory over Lesnar one year later, and his reign as the WWE Champion has been solid thanks to that victory.
Having Lesnar return in time for the build-up to WrestleMania and have him headline the show could benefit another Superstar. Even a hated Superstar like The Miz could end up becoming a crowd favorite if the creatives put him up against The Beast.
Brock Lesnar could return to pass on the torch to the next beast in WWE and decide to call it a day afterward. Allowing him to face McIntyre once again with the WWE Championship on the line could help cement The Scottish Warrior as the biggest force in the company.
