#3. A possible character change for Strowman?
Braun Strowman isn't a superstar who's in desperate need of a character change. The problem since 2018 was that he was hardly utilized in any major feud, let alone challenge for the World Championship.
He's one of those cases where a superstar can recover easily with a string of wins and great booking. An example of this is Bayley last year, who was in a much worse position than Strowman creatively. All it took was a move to SmackDown, a few good wins on the brand, a Money in the Bank win and a SmackDown Women's title win that very night. All of that happened in two months and it essentially helped her recover from 2 years of creative frustration.
Strowman may not need an outright character change, but we can see a scenario where he turns heel, but only if SmackDown is short on top heel superstars. 'The Fiend' Bray Wyatt is perfect for that spot, but perhaps a character tweak or a "tweener" status would best suit the Universal Champion.
