#2 Braun Strowman
It's understandable that Brock Lesnar and Braun Strowman have faced off numerous times in the past few years, but most of their matches were massive disappointments. Lesnar has defeated Strowman every time they faced and Strowman has struggled to recover from his losses against Lesnar. However, I think that Strowman deserved one final chance at Lesnar's Universal title.
Strowman is a monster and Lesnar is a beast. He is one of the most believable and plausible challengers to Lesnar's title. He is one of the few stars who can match Lesnar's immense strength and inhumane power.
Furthermore, Strowman has been gaining some momentum recently. He convincingly defeated Bobby Lashley in a Last Man Standing match and had an impressive showing in the All-Star Battle Royal. He has all the tools needed to defeat a champion of Lesnar's caliber.
Lastly, Strowman deserves to have a Universal Championship reign and Lesnar has been a thorn in his side for two years now. With WWE management backing Strowman, SummerSlam was the perfect time to crown Strowman the Universal Champion.
