I just never looked at Bulldog as a champion type guy. He could put on great matches and was physically imposing. But he just never seemed to really click as anything more than a mid card guy. And that's ok. He was a very good mid carder.
Maybe part of it is that he was never around for long enough. He was around from like 1990-1992 in his first solo run, but even within that 2 year time it seems he would disappear for weeks or longer at times. Could be wrong but that's how I remember it. Then he came back in mid 1994, but I don't remember him really wrestling much until '95. It just never really felt like he was "all in".
