Scott Irwin spent a good time of his career teaming up with his brother Bill Irwin in various promotions either in a mask as the Super Destroyer in the South or as one half of the biker team, the Long Riders. He was a tough customer who may not have been the most talented in the ring but looked like the guy at the end of the bar you would least want to mess with. Despite his success with his brother, it was with another partner early in his career, that he captured WWE Tag Team gold when he donned the persona of Eric; one half of the Yukon Lumberjacks. He died at the age of 35 from a brain tumor and likely would have had many good years in the ring left in him.
Oliver Humperdink had a few decent runs as a wrestler, but it was as a manager that he made his biggest impact. Humperdink was very successful in Florida and was a long time heel manager there. He did reach the WWE as a face manager of Bam Bam Bigelow and Paul Orndorff, but he was largely mute in that role and it was not an indication of his value on the ring apron. His place in the Hall of Fame is better viewed if they look at what he did outside of the WWE as opposed to inside of it.
