We're well past that utopian stage (if there ever was one) where wrestling shows are irrefutably reliant on wrestling alone. The purist, elitist mark chained dormant within us may vouch for three hours of wrestling only, but the modernistic aspect of our personality enjoys promos and spoofs because we, after all, are all human and spend our lives searching for ever-elusive entertainment.
Which is what non-wrestlers in WWE have to provide at all costs lest they be banished the Eric Escobar route. They need to be entertaining to compensate for their inability to throw punches or get kicked (or in Sin Cara's case, botch). It's a taxing and demanding job, and thus deserves extra adulations if done right.
Here's a look at four non-wrestlers who're doing some great work. Believe it or not, such creatures exist in WWE today.
Side note: Don't expect Santino Marella, he's a wrestler. You could have expected Brodus Clay, but he's not doing anything commendable.
