Big Cass

William Morrissey (born August 16, 1986) is an American professional wrestler currently signed to All Elite Wrestling (AEW) under the ring name Big Bill.

He is previously known for his tenures with WWE (where he performed under the ring names Colin Cassady and Big Cass), and Impact Wrestling (where he performed as W. Morrissey).

He is a former one-time AEW World Tag Team Champion.

William Morrissey was born in the Glendale neighborhood of New York City's Queens borough on August 16, 1986.

He is of Irish and German descent.

He attended Archbishop Molloy High School and served as a peer tutor, homeless shelter volunteer, and National Honor Society member.

He played basketball in his senior year and was featured in the Catholic High School Athletic Association Senior Classic All-Star game.

After graduating from high school, he received a scholarship to attend New York University (NYU).

He entered the pre-medical track before shifting to economics.

While attending NYU, he played as a center for the NYU Violets from the 2005–2006 and 2008–2009 seasons.

He co-captained the team for his final season.

After graduating from NYU, Morrissey founded a ticket brokerage specializing in events held at Madison Square Garden and Yankee Stadium.

Morrissey trained as a professional wrestler at Johnny Rodz's wrestling school in Brooklyn, New York.

He debuted in Rodz's World of Unpredictable Wrestling (WUW) promotion on May 30, 2009, under the ring name Big Bill Young with the gimmick of a cowboy, accompanying his storyline uncle Billy Walker to the ring.

His first match in WUW and in his career as a whole was on August 15, 2009, and he went on to wrestle a number of matches for the promotion before signing with WWE in mid-2011.

In June 2011, Morrissey signed with Florida Championship Wrestling (FCW), which was WWE's developmental territory at the time.

Morrissey made his first televised FCW appearance in July 2011, portraying the dean of the University of Florida.

Morrissey wrestled his first televised match under the ring name of Colin Cassady on the September 4, 2011, episode of FCW TV in a disqualification loss to Richie Steamboat.

Cassady found no immediate success, losing matches for the rest of 2011 and in early 2012.

Cassady scored his first win on the March 11 episode of FCW TV, defeating Kenneth Cameron.

Cassady's final FCW TV match was on July 7 in a win against Aiden English.

WWE rebranded its developmental territory, FCW, into NXT in August 2012.

In WWE, he came to prominence for his partnership with Enzo Amore, whom he teamed with from 2013 to 2017.

Cassady debuted on NXT television on June 5, 2013, with a loss to Mason Ryan.

Cassady then formed a villainous tag team with Enzo Amore, who had also previously lost to Ryan, and they labelled themselves "the realest guys in the room".

In real life, Cassady first met Amore at the age of 15, when they played basketball together at West Fourth Street Courts in Manhattan, New York.

Ryan defeated Amore and Cassady in consecutive singles matches, but lost to them in a handicap match.

Ryan ultimately had the last laugh when he caused Amore and Cassady to be attacked by Tons of Funk (Brodus Clay and Tensai).

Amore and Cassady then feuded with Sylvester Lefort and his stable of Alexander Rusev and Scott Dawson, turning them face in the process.

On the September 25 episode of NXT, Amore and Cassady participated in a gauntlet match for a future title shot at the NXT Tag Team Championship; they started the match and defeated Tyler Breeze and CJ Parker, then beat Rusev and Dawson, before falling to their final opponents, The Ascension (Conor O'Brian and Rick Victor).

Amore suffered a legit broken leg in November 2013, which led Cassady to try his hand at singles competition, feuding with Aiden English.

Amore returned on the June 26, 2014, episode of NXT, saving Cassady from an attack from Sylvester Lefort and Marcus Louis.

In early August, Amore and Cassady participated in a NXT Tag Team Championship number one contenders tournament, and they defeated Jason Jordan and Tye Dillinger in the first round, but were eliminated by The Vaudevillains (Aiden English and Simon Gotch) in the second round.

Lefort and Louis then renewed their rivalry with Amore and Cassady by attacking them and shaving Amore's beard and, as a result, Amore challenged Lefort to a match with the loser's hair as forfeit at NXT TakeOver: Fatal 4-Way on September 11, where Amore won the match, but Lefort ran away, leaving his partner Louis to lose his hair at the hands of Amore and Cassady.

Amore and Cassady proceeded to form an alliance with the debuting Carmella after the duo had accidentally cost Carmella her hairdressing job as per the storyline, causing her to demand to get a job as a wrestler.

Carmella had her televised in-ring debut on the October 16 episode of NXT.

Together, they won the NXT Year-End Award for Tag Team of the Year in 2015.

He was brought up to Raw alongside Amore the day after WrestleMania 32.

He was later moved to the SmackDown brand, where he had a brief feud with Daniel Bryan, before being released by the company in June 2018.

After leaving WWE, he resumed teaming with Amore (now known as nZo) on the independent circuit before joining Impact Wrestling in 2021, and AEW in 2022.
