#4 Jeff Jarrett
It would have been unheard of if you told any WWE fan that Jeff Jarrett would be inducted into the WWE Hall of Fame in 2018. Most of the WWE Universe remembers Mr. McMahon actually firing Jeff Jarrett on the air in 2001 on the last episode of Monday Nitro.
Moreover, there have been rumors that Jeff Jarrett blackmailed Vince McMahon for $300,000 right before he dropped the title to Chyna and his WWE contract was expiring. After WCW folded, he created TNA/Impact Wrestling which was a good alternative but didn't prove to be a game changer in the wrestling industry.
He is no longer part of the organization and was recently seen in the WWE Royal Rumble 2019. He even wrestled a match with Elias as well. Like others on the list, those once scorned by Vince have a way to come back into the fold. It would not be incorrect for Double J to say 'Ain't I Great.'
Jarrett also possessed a strong wrestling mind and has helped revolutionize the industry.
