Regardless, Hardy is still the most over wrestler in the company. Wrestling fans are interesting because sometimes a guy doesn't have to be a great wrestler or good on the mic to get over. Goldberg also was an example of this.
Well Hardy is good in the ring and has some kind of connection with the fans. I guess they just like him because he's his own guy with his own style or some shit.
Plus he's got star power from his time in WWE.
