#4 Former WWE Superstar Rob Van Dam
When Rob Van Dam joined the WWE in 2001, he was one of the most promising stars. At the time, WWE viewed him as the greatest wrestler of ECW. He went on to achieve great things, such as winning the Intercontinental Championship, Tag Team Championship, Money in the Bank, and even the WWE Championship.
However, WWE's busy full-time work schedule started to take a huge toll on RVD. This is why multiple former wrestlers, including Rob Van Dam, left the company in the first place. RVD's first run with the company lasted for a mere six years. In those six years, he dealt with a torn ACL, which put him out of action for a year and a 30-day suspension for violating WWE's Wellness Policy.
In an interview with ComicBook in 2019, RVD explained why he had to leave the company in 2007 and if he would ever return to WWE. He pointed out how overwhelming it was in his first run to work a full-time schedule. He felt that leaving WWE the first time was the right thing for him to do.
RVD even expressed how content he was on his blog when joining TNA back in 2010. He stated that he loved being in TNA due to a reasonable work schedule. Being able to work a part-time schedule was the reason why he decided to return to WWE in 2013.
Now that RVD is no longer working with IMPACT Wrestling, maybe the fans could see him have another run in WWE or even debut on AEW.
