Context paragraphs:
2002 Dallas Cowboys season: The 2002 Dallas Cowboys season was the 43rd season for the team in the National Football League.  It was Emmitt Smith's 13th and final season with the team, officially marking the end of the famed "triplets" tenure in Dallas after wide receiver Michael Irvin was forced to retire prematurely after the 1999 season and quarterback Troy Aikman retired prior to the start of the 2001 season.  All three players would eventually be inducted to the Pro Football Hall of Fame.  It was also the last of three consecutive 5-11 finishes for the Cowboys, beginning in 2000.

Brett Faryniarz: Brett Allen Faryniarz (born July 23, 1965) is a former professional American football player who played linebacker for seven seasons in the NFL.  In college, he was a defensive standout for the San Diego State Aztecs, starring on the team's much-maligned "Ocean Breeze" defense.  The name derived from a comment by former UCLA quarterback Troy Aikman, who compared the team's pass defense to "just playing catch in the open air."  Despite the defense's generally poor caliber, Faryniarz developed a reputation as a "solid quarterback sacker" and laid out Aikman twice during the SDSU UCLA game in the Rose Bowl.  After starting three years for the Aztecs, Faryniarz played for the then-Los Angeles Rams, where he played linebacker.  He finished his career on the inaugural Carolina Panthers team in 1995.

The game matched the Florida Gators of the Southeastern Conference against the UCLA Bruins of the Pac-10 Conference.  The Bruins were led by quarterback Troy Aikman.

1993 Cleveland Browns season: The 1993 Cleveland Browns season was the team's 44th season with the National Football League.  This season was notable for coach Bill Belichick deciding to bench, and then ultimately release, longtime starting quarterback Bernie Kosar in favor of Vinny Testaverde.  Kosar resurfaced during the season with the Dallas Cowboys, when he was part of the eventual Super Bowl champions as a fill-in for injured quarterback Troy Aikman.  The Browns get off to a 5-2 start despite the Quarterback Controversy.  Prior to the start of the season the Browns signed Free Agent Quarterback Vinny Testaverde.  Originally Testaverde was supposed to back-up his former University of Miami teammate Bernie Kosar.  However, when Testaverde performed better when given the opportunity to play some felt there should be a change at the Quarterback position.  However, the Browns went beyond that by unceremoniously releasing Kosar in the middle of the season.  The Browns lost their next four games and seven of their last nine games to finish with a 7-9 record.

The Sooners ended this season with 11 wins and a sole loss coming to the Miami Hurricanes in Norman, in a game in which the Sooners lost starting quarterback Troy Aikman for the season.  The Sooners were forced to place their trust in lightning-quick true freshman quarterback Jamelle Holieway and a physical defense featuring three All-Americans, who led them to a Big 8 Conference title and a national championship.
