Bowl Championship Series controversies: The Bowl Championship Series (BCS) was a selection system designed, through polls and computer statistics, to determine a No. 1 and No. 2 ranked team in the NCAA Division I Football Bowl Subdivision (FBS).  After the final polls, the two top teams were chosen to play in the BCS National Championship Game which determined the BCS national champion team, but not the champion team for independent voting systems (most notably the AP Poll).  This format was intended to be "bowl-centered" rather than a traditional playoff system, since numerous FBS Conferences have expressed their unwillingness to participate in a play-off system.  However, due to the unique and often esoteric nature of the BCS format, there had been controversy as to which two teams should play for the national championship and which teams should play in the four other BCS bowl games (Fiesta Bowl, Orange Bowl, Rose Bowl, and Sugar Bowl).  In this selection process, the BCS was often criticized for conference favoritism, its inequality of access for teams in non-Automatic Qualifying (non-AQ) Conferences (most likely due to perceived strength of schedule), and perceived monopolistic, "profit-centered" motives.  In terms of this last concern, Congress has explored the possibility on more than one occasion of holding hearings to determine the legality of the BCS under the terms of the Sherman Anti-Trust Act, and the United States Justice Department has also periodically announced interest in investigating the BCS for similar reasons.

Much controversy preceded the 1956 Sugar Bowl.  There was controversy over whether Bobby Grier from Pitt should be allowed to play because he was black, and whether Georgia Tech should even play at all due to Georgia governor Marvin Griffin's opposition to integration.  This stood in stark contrast to the 1956 Rose Bowl, which featured two of the most racially integrated college football teams of the day with six African American players for the UCLA Bruins and seven for the Michigan State Spartans.  Ultimately, Bobby Grier played making this the first integrated Sugar Bowl and is regarded as the first integrated bowl game in the Deep South.
