#2 He is a major draw even without the championship
If WWE is willing to cut a deal with Brock Lesnar allowing him to work for a limited number of calendar days in a year, there is no good reason to have him the championship of his shoulder. A Superstar of the status of Brock Lesnar doesn’t need to hold a championship to bring attention to his matches.
Triple H, John Cena, Undertaker, and now Shawn Michaels, all these men would be working for a limited number of days. But they still manage to bring attention to their storylines without drying out the championship opportunities for the remaining Superstars on the roster. The company needs to follow the same policy with Brock Lesnar as well.
If Brock Lesnar wins the Universal Championship again this Friday at Crown Jewel, it will be a waste of the most important championship on Raw.
