1. A WWE vs. UFC event
In years past, it would have been a pipe dream to imagine UFC and WWE co-promoting an event. Indeed, in the early days of MMA growing popular in the US, word was that the UFC had openly threatened WWE and its stars if they ever tried to emulate an MMA fight again.
Times have changed, though. The mainstream attention UFC has drawn has been instrumental in shifting WWE’s aesthetic to at times more realistic, or alternatively more spot-heavy to offer an alternative to MMA. On the flip side, UFC has embraced more showmanship like Brock Lesnar getting in Daniel Cormier’s face at UFC 226, besides the wild brawling that closed out UFC 229 and prompted some skeptics to suggest Dana White was walking the work-shoot line.
It’s no longer entirely unrealistic to imagine a show that included both WWE matches and UFC fights. Perhaps there could even a true crossover event between the two sides, most likely contested in a pro wrestling style on the premise that it would be easier to teach fighters to work functionally than to train a quorum of wrestlers how to fight competitively. It’s still a bit of a longshot, but Cormier coming over would invite such a concept to inch closer to a reality.
