#3 Jinder Mahal

We don't yet know how Jinder Mahal's reign will be perceived by future generations of fans, but for now, it seems to have been mixed.
Whilst some applauded WWE for giving Mahal an unpredicted push (especially when many fans complain about the shows being too predictable), many thought that the Modern Day Maharaja's push was down to the WWE's deals with India.
Look who just shut down all of Tony Khan's critics! More HERE.
If the latter is true, then the WWE no doubt regret pushing Mahal, as his reign didn't seem to affect the Indian market much, with low ticket sales for the company's tour in the sub-continent whilst he was champion.
Back in the States, ticket sales with Mahal as champion weren't much better, and whilst it'd be unfair to put the blame solely on Jinder, his successor AJ Styles certainly did better as WWE Champion.
