Big Cass is back in WWE eight years after his first run with the company came to an abrupt end.
Cass, whose real name is William Morrissey, originally rose to prominence alongside Enzo Amore as one of WWE’s most popular tag teams. The two eventually split, with WWE positioning the nearly seven-foot Cass for a singles push before releasing him in June 2018.
After rebuilding his career outside WWE, including runs in TNA as W. Morrissey and AEW as Big Bill, Cass has received another opportunity with the company.
So, why did Big Cass leave WWE in the first place?

Why Did WWE Fire Big Cass in 2018?
WWE announced on June 19, 2018, that it had released Big Cass. The company’s statement offered no explanation, simply stating that it had “come to terms” on his release.
Reports at the time indicated, however, that Cass’ departure followed a series of backstage and personal conduct issues.
One notable incident occurred during a May 2018 episode of SmackDown. Cass participated in a segment involving a little person dressed as Daniel Bryan. According to reports, Cass wanted to extend the planned attack beyond a big boot but was told not to by WWE officials and Vince McMahon.
Cass reportedly went ahead with the additional attack anyway, creating significant backstage heat.
The SmackDown incident wasn’t reportedly the only factor. Reports following his release pointed to concerns about Cass’ personal conduct, including excessive drinking and issues during a WWE European tour.
Morrissey later publicly discussed his struggles with alcohol and mental health. He eventually rebuilt his career, competing in TNA as W. Morrissey and AEW as Big Bill before making his way back to WWE.
Could Big Cass Become a WWE World Title Contender?
Personally, I’m excited to see Cass get another opportunity in WWE. I was a huge fan of Enzo Amore and Big Cass during their original run and thought the team had the potential to eventually reach the level of a team like the Hardy Boyz in terms of popularity with WWE fans.
That obviously never happened, but Cass now has an intriguing second chance as a singles star.
WWE could use more physically believable heels, and at nearly seven feet tall, Cass certainly checks that box. Presented correctly, I think there’s a path for him to eventually become a credible world championship contender.
The key will be what happens after the initial excitement surrounding his return wears off. His size and presence immediately make him stand out, but his character will need to evolve beyond the returning monster heel presentation if WWE wants fans to continue viewing him as a serious threat at the top of the card.
Cass has already proven he can rebuild his career. His second WWE run will determine just how high his ceiling really is.
