He is a kilt-wearing pro wrestler and he is legitimately from Scotland. No, he is not Roddy Piper. He is Derek Graham-Couch (aka Robbie McAllister). Together with Russell Murray (aka Rory McAllister), they formed the Highlanders in the WWE.
The Highlanders seemed to be stuck in midcard limbo (sort of like the old Bushwhackers), before their release from the WWE. They came on the scene with some promise and hype, but quickly faded. I think this was another poorly executed story plan from the WWE management.
It didn't help Robbie's career when he was shown on TNA's tv broadcast while still under WWE contract. He was only shown in the crowd, but that is not exactly what the WWE likes to see.
I met McAllister accidentally while in Novi for the Motor City Comic Con. He happened to be at a convention in the same building. McAllister was appearing with another former WWE wrestler who also was mishandled, Kizarney (see earlier post). In fact, both men were the camera men for my picture with the other.
