During a recent episode of his Grilling JR podcast, Jim Ross discussed Jeff Hardy and why he was held back from becoming a long-term WWE world champion. 

Hardy held the Heavyweight Championship and the WWE championship once with a combined reign of fewer than 70 days.

"There is no reason that Jeff Hardy would not have been a great WWE Champion or any title. But he just wasn’t reliable. And how do you put your championship on somebody you don’t have full confidence that they are going to be cool. They are going to be okay. Can they take the pressure of being the champion? Can they take the pressure of going on last night after night? 

Can they take the pressure of putting their company on their shoulders and marching forward? And at that time, that was not what everybody thought, they just didn’t think Jeff was going to be able to hold on in the scenario."
