The 2000 Montreal Alouettes finished in first place in the East Division with a 12–6–0 record.
 This was Anthony Calvillo's first season as the full-time starter, and he didn't disappoint, having an allstar year, first leading his team to the Grey Cup, by beating the Winnipeg Blue Bombers 35-24 in the East Final, as they appeared in the Grey Cup for the first time since 1979, but lost to the BC Lions, who were led by Damon Allen.
 Overall it was a great year for the Alouettes, even if they lost the Grey Cup.
The 1991 Los Angeles Raiders season was their 32nd in the National Football League (NFL).
 They were unable to improve upon their previous season's output of 12–4, winning only nine games.
 After a 9-4 start, the team lost its last three games, but did qualify for the playoffs for the second straight season.
 The Raiders were inconsistent offensively, with struggling quarterback Jay Schroeder eventually benched in favor of rookie Todd Marinovich.
 It was notable that future Hall of Famer Marcus Allen's role was restricted mainly to backing up newly acquired Roger Craig, and future All-Pro Tim Brown also played mostly as a reserve, starting only one game.
 The loss of Bo Jackson to a career-ending inury also clearly had an impact.
 A solid defense was led by Howie Long, Greg Townsend (13 sacks) and another acquisition from Northern California as the Raiders played in LA and not Oakland as some people have forgotten , Ronnie Lott (8 interceptions).
Marcus LeMarr Allen (born March 26, 1960) is a former American football running back and football analyst for CBS.
 As a professional, Allen ran for 12,243 yards and caught 587 passes for 5,412 yards during his career for both the Los Angeles Raiders and the Kansas City Chiefs from 1982 to 1997.
 He scored 145 touchdowns, including a then-league-record 123 rushing touchdowns, and was elected to six Pro Bowls over the course of his career.
 Allen was the first NFL player to gain more than 10,000 rushing yards and 5,000 receiving yards during his career.
The Heisman curse is a term coined to reference a two-part assertion of a negative future for the winning player of the Heisman Trophy.
 The "curse" supposes that any college football player who wins the Heisman plays on a team that will likely lose its subsequent bowl game.
 The trend of post-award failure has garnered the attention of the mainstream media.
 Talk of a curse in relation to bowl results was particularly prevalent from 2003 to 2008, when six Heisman Trophy winners compiled a cumulative 1–5 bowl game record, and five of those six led number one ranked teams into the Bowl Championship Series (BCS) National Championship Game as favorites (Heisman Trophy winners, including Reggie Bush, who gave back his Heisman Trophy, are 4–8 overall in the BCS National Championship Game and College Football Playoff National Championship, although prior to 2009 they were 1–6).
 Additionally, the Heisman curse asserts that in most cases a Heisman winner will have either a poor career in the National Football League (NFL), or in fact not even see such a football career at all.
 Although many Heisman winners have not enjoyed success at the professional level, including players like Matt Leinart, Andre Ware, Jason White, Rashaan Salaam, Eric Crouch, Ty Detmer, Troy Smith and Gino Torretta, proponents of the "curse" rarely cite highly successful players such as Barry Sanders, Charles Woodson, Eddie George, Tim Brown, Bo Jackson, Marcus Allen, Earl Campbell, and Tony Dorsett among the notables.
