#3 Cole was almost accidentally signed by WWE in 2010
Adam Cole has been wrestling ever since he was a child, he made his wrestling debut when he was 19 years old and has been around the wrestling scene ever since. Cole has competed in companies including Ring of Honor, Combat Zone Wrestling, Pro Wrestling Guerrilla and Evolve.
Many believe he didn't make it onto WWE's radar until he signed with the company back in 2017, but this isn't the case. Cole had been making waves all over the world years before this and had tryouts with WWE dating back to 2010 when he had only been wrestling for two years.
In 2010, he worked backstage on SmackDown where he was seen in a bar drinking with Straight Edge Society's Serena Deeb. This was because WWE was looking to sign Austin Watson who is Xavier Woods, and accidentally almost signed Adam Cole, who's called Austin Jenkins, so they offered him a spot on SmackDown as a way to apologize.
The company later came knocking in 2013 where he attended tryouts at the Performance Centre in Florida, but wasn't signed for another four years.
