We recently noted about Vince McMahon souring on Braun Strowman over his in-ring work just not being where it needed to be. According to a source close to Strowman, he, like Bray Wyatt, thought he was getting Brock Lesnar at Wrestlemania 32. The feeling is he hasn’t been as motivated since learning he wasn’t getting the match.
As one source put it, this was classic Vince McMahon mind games. Vince had told Bray and Braun at different points they were the favorite to land Brock in a match at Wrestlemania. Vince hoped it would fire them up and get the competitive juices flowing. This is something is done in the past with other guys, purposely creating friction. Think of what he did with Bret Hart and Shawn Michaels a couple decades ago.
In the end, both Bray and Braun got swerved and neither got the match.
