#3 Braun Strowman

In early 2019, Braun Strowman set his eyes on the WWE Universal Title that Brock Lesnar held. The Beast had defeated Strowman in their match at WWE Crown Jewel and the Monster among men was keen on payback.
On an episode of Monday Night Raw, Strowman stood in the ring while Paul Heyman and Brock Lesnar conversed with him from a backstage area. Unfortunately, Braun forgot his lines during the promo and the fans could sense the awkwardness in the air. For several seconds during the promo, Braun, as well as Brock Lesnar, just looked at each other, while not speaking a single word.
Heyman, a legit master of the mic, tried to save the promo, but apparently, it wasn't enough. Finn Balor went on to replace Braun Strowman for a shot at the Universal Title at the Royal Rumble.
Promos aren't Strowman's strong suit and that is one department he has to massively work on.
