#4 Matt Morgan's stuttering gimmick
One of the most intimidating wrestlers to ever step foot in a WWE ring, Matt Morgan had tons of potential. He didn't do much of note during his WWE stint though, which lasted around three years. Morgan returned to WWE TV in April 2005, after being on the sideline for over a year. He donned a new gimmick which saw him stutter while cutting promos and get defensive over the same.
Years later, Morgan opened up on Vince McMahon coming up with the idea and stated that even though he hated it, he had to go ahead with it because it was Vince's creation.
As for the stuttering thing, I did say in that office, and not talking back or anything, but you know, Vince sold this to me as he's always wanted to put this stuttering character on one of these bigger, super impressive looking guys."
I wasn't a fan of it, but when Vince comes up with an idea, you gotta go with it.
Morgan was paired with Carlito, and he helped him defeat The Big Show at Judgement Day 2005. The association didn't last long and Morgan was released by WWE in July.
