#4. The Miz

It is sad to say that WWE has not used The Miz well after his babyface-turn a few months ago. Sure, the "A-lister" had a hot WrestleMania 35 feud against Shane McMahon. But now, he is nothing but an afterthought. It is safe to say that WWE has dropped the balls with one of its best talkers on the mic right now.
The Miz needs an opportunity to redeem himself and a Universal title match at SummerSlam 2019 (against Seth Rollins) would be a great way to start it. The Miz does not need to win the match but a marquee matchup at the biggest event of the summer would definitely help The Miz to kickstart his career. It could even help him to turn heel on Rollins, finally allowing him to do what he does the best in WWE - speak frankly about the wrestlers.
