The issue is not whether Jones can be an even more negative Felger. The issue is that he's boring as f***. You can predict his take 100% of the time. Just assume the most negative, most unreasonable/unfair/uninformed opinion possible and you always know what he's going to say.
Felger might be a heel, but he'll surprise you sometimes by being reasonable or even starngely positive. That's what makes him a good hell. Sometimes you totally agreed with Mr. Perfect, Ric Flair, or Roddy Piper! Hell, Bobby Heenan wasn't always negative, which is what made those compelling. You actually had to listen to them, even if you hated what they said most of the time. Sometimes they'd say something and you'd think, "Okay, he has a point."
Jones is a caricature of a caricature and it's so f***ing boring. He's gonna bomb there long term.
