We should be grateful for Sin Cara while he's still around - and he probably won't be for very long, if current form is any indication.
He was once protected by his marketable mask, and the merchandise sales that came with it, but there's about three other masked men on the roster these days. He has lost his status as special attraction - and, if we are to believe the recent rumours, he's lost his marbles.
On WWE's recent European tour, Cara, known backstage agitator, thought it would be funny to make some (unspecified) odd noises. Locker room leader Jericho echoed the muted sentiments of his peers by telling him to "Shut...the hell...up!" He probably didn't wheel out his Attitude Era catchphrase, but this story has already been embellished. Cara's response? "F*ck off." How pleasant. A scuffle ensued, the details of which are sketchy, but noted psychologist Jericho at least had the nous to work over a suspect body part by biting Cara on the finger.
As Jim Cornette has it, in the post-kayfabe era, wrestling has been pasteurised and sanitised for your protection. Wrestlers in 2016 don't stab each other with scissors in hotel rooms or inject themselves with monkey hormones. They play video games backstage and take selfies.
Cara is the glorious, quick-tempered exception - and it's little wonder there's much about him WWE wants you to forget.
