As the son of Afa of the Wild Samoan, Samu reached the big time early as the third member of the Samoan clan and even helped to defend the WWF World Tag Team Title when Sika was on the shelf for a bit. Despite his young age, he was not out of place and held is own against much more experienced competition. He would later team with his cousin Fatu and form a devastating tag team (The Samoan SWAT Team in NWA and the Headshrinkers in WWE). Samu was a decent tag team wrestler, but as he did not go in with Afa & Sika, and with Fatu’s career eclipses his, it does not seem likely for this Samoan to get in.
Brian Adams was brought in as “Crush” to replace an ailing Ax in Demolition. The last incarnation of Demolition just wasn’t the same, but Brian Adams would remain tied to the WWE for years after with various incarnations of the Crush gimmick and had a stable role in mid card feuds. He was big enough to work as a monster yet not too big to work effectively with smaller wrestlers in even give and take contests. Adams would later go to WCW where he languished until his Kronik pairing with Bryan Clarke. That tandem had a failed final run in WWE and Adams wasn’t seen after. He has since passed away, but he had a very solid career in pro wrestling. It may not be Hall of Fame material though.
Austin Idol began his career as a power wrestler, which stood to reason considering he competed as a Power Lifter in the Super Heavyweight division. But we know the adage of strongman wrestlers, who although are marketable are rarely any good. After a plane crash that sidelined him, he remerged significantly lighter, with a new look, and the moniker of the “Universal Heartthrob”. The new persona was a winner, and though he was not on a national stage he was a draw in Southern promotions and feuded often with Jerry Lawler. Had Idol had a shot in the WWF, he could very well have done well there.
The first time that Tom Prichard arrived in the WWE it was as one half of the Heavenly Bodies with Jimmy Del Ray. It took the “Doctor” a long time to get there as he toiled in the Indies, the USWA and Smoky Mountain in numerous roles for over fifteen years. By the time he reached the National stage it was clear to anyone looking that he was already a seasoned pro and a ring general. He eventually won Tag Team gold in the WWE (albeit with a different partner), but his real contributions continued after his ring retirement where he has performed a trainer for the WWE for years after. It is this role that could see him as a dark horse Hall of Fame candidate.
