#4 Winning streaks often become losing streaks
Remember when Ryback had a lengthy winning streak in 2012 before he faced CM Punk for the WWE Championship at Hell In A Cell? Well, including that main-event loss, his run of victories became a run of defeats and he ended up losing his next eight matches on pay-per-view.
A similar thing happened to Asuka following the end of her 914-day undefeated streak at the hands of Charlotte Flair at WrestleMania 34. Within two weeks, she lost a tag match on SmackDown Live against The IIconics, and within three months she had lost two singles matches against Carmella.
In Rusev’s case, his one-year winning streak in 2014-15 turned into a mix of wins and losses between 2015-16, and from 2017 onwards he has only ever lost on pay-per-view.
Granted, his losing streak has lasted a lot longer than Ryback and Asuka’s winless runs after their undefeated streaks came to an end, but there is definitely a running theme in WWE where these unstoppable Superstars begin to lose a lot more than expected when their streaks are over.
