#3 Braun Strowman

Braun Strowman is rumored to be Goldberg's opponent for WrestleMania 36 after Roman Reigns pulled out of the event. The Monster Among Men, who had a great 2018 and was pipped to hold aloft the Universal title when he was on RAW, didn't have a great 2019.
But, he could turn things around for himself this year, if he can win the title at The Show of Shows. If he does win, it would set it up beautifully for a feud against his former Wyatt Family partner, The Fiend. Wyatt and Strowman are close friends in real life and they could use that bond to put on a great story on SmackDown.
The two faced off at Starrcade in December last year, but that was a one-off match with no real storyline. A feud between the two could also help WWE eventually put on a match between The Fiend and Roman Reigns, which is what their final goal has been for a while now.
