#7 Rob Van Dam - 22 days
In terms of popularity, things don't get much bigger than Rob Van Dam in his prime. The high flyer was considered to be one of the most underrated superstars in the history of WWE before eventually getting his big win, defeating John Cena to become the WWE Champion.
The reign, however, didn't last long, as rumours of a wellness violation saw him lose the strap just over three weeks later to Edge in a Triple Threat match also involving Cena.

It's a shame in a lot of ways that this happened, considering how popular RVD was, but at the same time, you've got to respect the rules put in place by the company.
Naturally, they didn't put the title back on him due to trust issues, but considering the fact that his popularity was still through the roof it's surprising that they didn't consider putting things to one side. After all, RVD possesses the ability to have a strong match with just about anybody.
We once again go into the past for this next entry.
