Sgt. Slaughter revealed in an interview with Arda Ocal at the Cauliflower Alley Reunion in Las Vegas, Nevada that he was in the original plans to manage Jack Swagger. Slaughter said plans were changed when Rey Mysterio and Sin Cara were lost to injury and Alberto Del Rio was turned babyface. This resulted in the creation of the Zeb Colter character to push the duo as antagonists.
Slaughter said the original storyline was for him to "put Swagger through bootcamp" and build him as the protagonist. He would welcome an opportunity to return to WWE as an on-air character and his bags are always packed. Slaughter is currently working for WWE as an ambassador.
