With men like Apollo Crews, Cage and more taking the belief of what big men can to new heights, Willie Mack has been somewhat forgotten in all of this. Mack was signed to a WWE developmental deal in 2014, but after passing the medical tests he was mysteriously released before even making it to NXT. Mack performs in Lucha Underground as The Mack, and he hasn't lost any of the undeniable charisma that made him one of the most popular independent wrestlers in the early part of his career. His in-ring style is more akin to a luchador, with the odd memory of his size kicking in. The perfect opponent for Rey then! Mack taking on Rey Mysterio is the sort of match that Rey signing with Lucha Underground means must happen. As an introduction to Rey and Rey in the product, Mack is the perfect opponent.
