A few others in the mix......Skandar Akbar, Sir Oliver Humperdink and Percy Pringle.
In regards to Ellering. I think he was a perfect compliment to the RW's and actually did serve as a real manager, not just on camera. and when he started out in GCW, he had an incredible stable....the original Legion of Doom w/Spoiler, Bundy, RW's, etc... as well.
JJ Dillon also served as more of a "real" manager to the Horseman. What I really thought he did best for them was give them that voice of "business as usual" and blended so well with the Horseman's bragging about their lifestyle.
Jim Cornette with the Mid-Night Express was incredible. Neither guy, regardless of the team, could talk at all and he got them over big-time.
Man, these lists just remind me of how far things have fallen. Almost ALL of these guys really enhanced the product, not just walk to the ring and stand around. Sad era to see gone.
