#5 Gran Metalik
WWE is dropping the ball with a lot of the Cruiserweight Division. In fact, both Austin Aries and Neville left the WWE entirely due to the company's mishandling of the division. But it's not just them - talents that were once "top tier" in the Cruiserweight Division, such as TJ Perkins, Brian Kendrick, and Rich Swann, have since become afterthoughts. But there is no Cruiserweight who has fallen further than Gran Metalik.
You know...Gran Metalik? The former Máscara Dorada? The runner-up of the Cruiserweight Classic? The guy who beat tournament favourite and legit-best-technical-wrestler-in-the-world-today Zack Sabre Jr. to get to the finals? No? Probably because they've used him so sparingly since his signing.
Despite being announced as a member of the Cruiserweight Division back in September, Gran Metalik didn't make his official debut on 205 Live until February, this year. He would appear every now and again on the main events in arbitrarily-thrown-together tag team matches, then he'd spend the entirety of May and June staring at the lights for lower-card talents, such as Noam Dar, Ariya Daivari, and Tony Nese. Since then, he has wrestled almost exclusively in random tag matches, in which he very rarely (if ever) got the pinfall. He has lost his two singles matches in three months, one to Neville and the other to Drew Gulak.
Gran Metalik's booking goes beyond just being bad - it's entered the realm of "unacceptable". I only hope that WWE realizes what they've got in this guy before it's too late.
