- Dolph Ziggler
Dolph Ziggler is the poster boy for badly booked superstars. The former male cheerleader/Chavo Guerrero’s golf caddy is one of the best technical wrestlers in the WWE, one of the best sellers in the WWE, and very few wrestlers, male or female, have a connection with the crowd like he does. However, the company has never truly gotten behind Ziggles and his considerable talent, often leaving him with nothing to do for long periods of time. While his feud with the Miz over the Intercontinental title was one of the best of 2016, it wouldn’t be a surprise for him to become less and less important to the Smackdown ecosystem, as is the WWE way. He’s had two world title reigns, but they were mostly uninspired and poorly booked. Now, at 36 years old, he has a burgeoning comedy career outside of the WWE and it wouldn’t be crazy to see him leave the ring behind to explore other avenues. It’d be a damn shame, but no one would blame him.
- Rey Mysterio
One of two non-WWE wrestlers on this list (For the moment, at least; he could pop up at anytime and no one would be surprised), Rey Mysterio has a ton of mileage on him. He’s 42 years old and has been wrestling for an astonishing 28 years. He’s wrestled for AAA, ECW, WCW, CMLL, WWE, and, most recently, Lucha Underground. As a result, he has an injury history a mile long and his knees may be the worst this side of Kevin Nash. The question of if Rey Mysterio will retire isn’t so much “will he?”, but “when will he?” He doesn’t have anything else to prove: he’s a two time World Champion in WWE, a WWE Triple Crown Champion, a Royal Rumble winner, and one of the most beloved high fliers, and baby faces, to ever step into the squared circle. Putting Rey against a big star is an instant big money match for any promotion and he’s admittedly still good in the ring, but his time is limited.
