#4 Big Cass angers Vince McMahon after going off-script during Danel Bryan feud on WWE SmackDown

Big Cass had tons of promise, but his WWE career ended in controversial fashion and we never got to see him become a top star on one of the main brands. In 2018, Big Cass kicked off a feud with WWE veteran Daniel Bryan, with Cass being a heel at the time. Bryan had come out of retirement mere weeks ago, and the WWE Universe was supporting the former World Champion during the feud.
In a SmackDown segment, Big Cass was set to hit a Big Boot on a little person, dressed as Bryan, but Cass ended up doing much, much more. He threw a series of punches at the guy, and Vince McMahon was livid beyond belief.
"This was specifically designed to get me uber, uber heat. Then I was panicking because I was like, 'This is not the reaction they want.' So then I did what I thought was right, I got back through the curtain, it was very, very bad. It was a bad night for me."
"That is the understatement of the century. Furious… he was furious. That was the first straw, rightfully so. That was such a bad decision. So stupid."
Big Cass' WWE career soon came to an end, and he hasn't been much active in pro wrestling ever since then. Cass and Enzo Amore were two incredibly talented Superstars, and the WWE Universe hadn't imagined in its wildest dreams that both men would be out of WWE by mid-2018.
