I doubt it is possible to be a Vol fan and not understand why you're skeptical.
My hope lies in a couple of things primarily.
One, I think Pruitt is a pretty good coach. I think he is a football coach after watching Jones' coach by cliché non-sense for the last 5 years. The guy really seemed to think that yelling clichés at players and getting them to repeat them would somehow turn into execution.
Two, while I don't think Jones did a whole lot else well, he brought in some talent. The fact that he underproduced so badly with that talent actually boosts my hopes some now. Starting with the first year, Jones never got the most out of a UT roster. He didn't even get the sum of the talent out of a roster. They often lost games they shouldn't have lost or suffered tight games against inferior opponents. It is debatable if he ever truly beat a team that he shouldn't have beaten at UT. Teams that beat him and won more games in the SEC... put fewer players into the NFL... had consistently lower rated recruiting classes. By any measure I can think of, he underperformed the talent he had. If Pruitt and staff can coach... they've got something to work with. That's all I'd give Jones credit for... but that's fairly significant to my hopes for success this year.
