Not so silent Bob said:
The ultimate Warrior beat Hulkamania at its height. Hardly a bad champion. He didnt kick on like it was thought but he deserved a run.
Bob Backlund was a great, wrestler before Hulkamania, an all time great. Definitely not a bad champion.
JBL is a tag team wrestler who loses every major singles match he ever fights but now is somehow supposed to be believable as a champion. He is absolutely the worst champion ever that i can think of. I would prefer Steve Lombardi, Barry Horowitz or Moondog Rex.
Others, Vince McMahon comes to mind. He is not even a wrestler (alhtough come to think of it, was he ever a champion?)
