Jeff Jarrett has been perceived as more of a star by WWE audiences in 2019 than he ever was at any previous time in WCW or WWF, right? How is there a nostalgia pop for someone who never got any sort of pop outside of Tennessee in the first place? Isn't the reaction to Jeff Jarrett at the Royal Rumble and on Raw the most obvious example that WWE crowds just want to see something different than the same cookie-cutter shows they produce every week with the same 50/50 characters?

Clearly.  As long as he never wears that outfit from the Rumble again, I'm fine with him as an onscreen character here and there.
