#4 Jack Strong (Jack Swagger)
Billed as the next Brock Lesnar, Jack Swagger quickly rose through the rank in the WWE. He won the ECW Championship a mere three months after debuting on the main roster. Swagger would go on to win the Money in the Bank at WrestleMania 26 and would cash in his contract on Chris Jericho to become the World Heavyweight Champion but he wasn't able to hold on to the title for a long time and lost it to Rey Mysterio at the Fatal Four Way in 2010.
Swagger would go on to win the United States Championship once and would have a decent run as a face run alongside Zeb Colter as part of The Real Americans but wasn't able to reach the main event spot again. He asked for his release from the company in March 2018.
After leaving the company, Swagger would start working for various Indy promotions like 5 Star Wrestling and House of Hardcore. He is currently working for Lucha Underground where he is the current Lucha Underground Champion and has also signed to Bellator MMA, where he will be competing in the Heavyweight division.
