Shivers played for seven years in the NFL before he began coaching at
Merritt College in
Oakland, California. He also coached at the
University of Nevada,
University of Hawaiʻi at Mānoa and the
University of Nevada, Las Vegas (UNLV), after which he accepted a job as an assistant coach for the
BC Lions in the
Canadian Football League (CFL). Shivers stayed with the Lions for six seasons and rose through the ranks of the Lions' front office. In 1985, the Lions won the
Grey Cup. In 1989, Shivers left for the
Calgary Stampeders to become the team's U.S. scout. In 1991, he became the team's assistant
general manager. Calgary won the
Grey Cup in 1992. In 1995, Shivers left to become the General Manager of the expansion
Birmingham Barracudas, but the team folded after one season, as did the rest of the American expansion teams. Shivers returned to Calgary in 1996, again as assistant GM. Calgary won the Grey Cup again in 1998 under head coach
Wally Buono.
Saskatchewan Roughriders Shivers became General Manager of the
Saskatchewan Roughriders on December 24, 1999, with his first two years at the Riders' helm being a struggle on the field. aided mostly by hosting the Grey Cup Championship Game, and by the provincial government forgiving over $1 million of debt. Nevertheless, rising attendance also played a significant part as Shivers had restored respectability to the Riders which excited the fans to come out in greater numbers. The Riders had also made the playoffs in four straight years, including two Western Division Finals in a row (2003–2004). However, in the later years of the franchise under Shivers' helm as GM, the team seemed to hit a wall or ceiling of progress, and their record stagnated instead of improving.
Controversies mount and stagnation Mired in back to back .500 seasons (winning percentage-wise) in the years 2004 and 2005, the Riders exited the playoffs early and were seen by most fans as not living up to their expectations. Many blamed the coaching, while others pointed their fingers back to when Shivers failed to re-sign Henry Burris, who moved onto success with the rival
Calgary Stampeders. This upset many Rider fans greatly, as the Calgary Stampeders ended up rebuilding rapidly, going from being a poor team in the 2004 season to a second-place finisher in the Western Conference of the CFL in season 2005. Rider fans began to voice their displeasure at the time it was taking the Riders to achieve similar goals, like finishing first or second in the West, and hosting a home play off game. This was compounded by starting quarterback, Nealon Greene, becoming increasingly inconsistent in the 2005 season, as Head Coach Danny Barrett dropped him for poor play in favour of Marcus Crandell, their back up quarterback. Discontent grew even further with various off-the-field incidents involving the Rider players during and following the 2005 season.
Trevis Smith, a starting Rider
linebacker on the defence, was charged with
aggravated sexual assault on October 28, 2005, accused of having repeated sexual encounters with women, one from
Regina, Saskatchewan and one from
British Columbia, despite knowingly being
HIV-positive. It was one of the biggest controversies and embarrassments ever faced by the Roughriders in their history as it made national headlines from coast to coast. Many people pointed the finger at Shivers once again, whether right or wrong, seeing Shivers as an unwilling figure in instituting a player code of conduct. The naysayers and blamers felt Shivers should have more control over his team's behaviour. Shivers defended himself by saying what happened with Smith was a societal problem, not a football one. Further tarnishing the team's image was the arrest of
Kenton Keith, a Riders
running back, for aggravated assault at a Regina nightclub, on July 12, 2006. others maintain that personal individual responsibility supersedes the control Shivers or any other Riders' management should have over the players. This is precisely the argument put forward by Shivers, as he views many of these things as societal issues, and not football ones.
A mixed record Shivers' first major decision as the Riders' General Manager was to hire his
coach Danny Barrett, a man with no prior CFL head coaching experience, or head coaching experience at any level. "The one thing I did right was (hire) Danny Barrett. He's a good young black coach. Most of our guys are young black kids. We've got a head coach our people like to play for", Shivers said. Shivers had been known to speak his mind on issues facing his team and was not afraid to criticize players when he perceived a lack of effort or poor play. This served to motivate the team often. One situation which some fans view as controversial in Shivers' tenure is his failed negotiations with quarterback
Henry Burris. Burris was a free agent in the spring of 2005 after the team narrowly lost the Western Final to the BC Lions the previous November. Burris was uncomfortable with the then back-up quarterback Nealon Greene remaining on the roster. He wanted a commitment to be named the clear starting quarterback for the Riders. Despite being offered the richest contract in club history at the time, Burris chose to accept a more lucrative offer from the Calgary Stampeders. It was never clear if Burris was actually promised the starting quarterbacking position with the Riders, as many contradictory statements were made regarding this matter. Burris also maintained that the Riders offered him less money than Shivers had publicly stated. Many point to the failure to re-sign Burris, rightly or wrongly, as being the beginning of the end for Shivers as the general manager of the Saskatchewan Roughriders.
Fired by the Saskatchewan Roughriders Shivers was fired by the Saskatchewan Roughriders'
board of directors as there was a concern that the Riders had regressed, a lack of progress was being made in signing players who would be free agents in 2007 to extensions, plus Shivers was not comfortable with the new power structure of the Riders to be implemented in 2007. At the time of his firing, the board of directors, led by the
President and
CEO Jim Hopson, openly expressed their displeasure at the lack of progress on thirteen soon-to-be Rider free agents not being signed for the 2007 season. In total, 30 Riders were about to enter the option years of their contracts in season 2007, with not one of them signed to future contracts halfway into the 2006 season. Many balked at this statement, however, as other CFL teams also had a large number of players going into their option years in season 2007. However, alarm bells were also being sounded as the Riders were also committed to $4.5 million in salary, well over the new $3.8 million salary cap to be instituted by the CFL in 2007. Thus, Shivers was fired from his post as general manager on August 21, 2006, with the board unanimous in its decision to fire Shivers. During his era as Riders' general manager, Shivers lived part-time in Regina, the home of the Roughriders during the season.
BC Lions On January 28, 2008, Shivers was hired as the director of player personnel for the
BC Lions. This reunited him with Lions GM/Head Coach Wally Buono, with whom he worked during their tenure with the Calgary Stampeders in the 1990s. On June 21, 2022, it was announced that Shivers would be enshrined in the
Canadian Football Hall of Fame in the Class of 2022 as a builder. ==CFL GM record==
