7. Alberto Del Rio
Right from the beginning, Alberto Del Rio was shoved down fans’ throat. Instead of him slowly climbing up the ladder, he was immediately thrust into the main event scene and fans wanted no part of it.
He debuted in June of 2010 and won the Royal Rumble in January of 2011. A couple of months later he was contesting for the World Heavyweight Championship. His push happened way too soon that it felt underwhelming at times.
People just stopped caring about his character. Eventually, he won the World Championship, but fans still didn’t care. After multiple failed attempts to get Del Rio over with the crowd, WWE gave up on him.
Del Rio started gaining some reaction from the crowd when he was moved down to the mid-card which makes me wonder what would have happened if they had built up his character naturally.
