Document 12: Magnolia Bowl: The LSU–Ole Miss football rivalry, renamed the Magnolia Bowl in 2008, is an American college football rivalry game played annually by the LSU Tigers football team of Louisiana State University (LSU) and the Ole Miss Rebels football team of the University of Mississippi (Ole Miss). The teams compete for the Magnolia Bowl Trophy. The Tigers and the Rebels first met in 1894, and have been regular opponents in Southeastern Conference (SEC), meeting annually since 1945. The rivalry was at its height during the 1950s and 1960s, when both teams were highly ranked and during which time both teams claimed a national championship. The rivalry died down from the 1970s to the 1990s, owing to Ole Miss not returning to conference or national prominence since the 1970s and because LSU has seen new rivalries emerge when the SEC split into two divisions in 1992, most notably Alabama, Arkansas, Auburn, and Florida. Even though the rivalry has not attracted the same national attention in recent years, it still stirs up passion in both Oxford and Baton Rouge.
Document 13: Hey Reb!: Hey Reb! is the mascot for the UNLV Rebels, the athletic teams of the University of Nevada, Las Vegas in Paradise, Nevada, USA. He performs live at all UNLV athletic events. The campus community is divided over the contention that the mascot, looking like a confederate soldier, appears to be a symbol of racism. The mascot was first created in 1983 to depict the embodiment of an independent, rebel spirit at UNLV athletic events. As race discrimination issues dominated national events, community members voiced concerns that Beauregard glorified the Confederacy and had little to do with the community's history. In the early 1970s, students voted to banish Beauregard but retained the Rebels name (rejecting alternatives such as Big Horn Rams, Nuggets, A-Bombs, and Sand Burners). Replacing Beau was a musket-toting Minuteman, but that Revolutionary War figure didn't resonate in the West either. So UNLV essentially went without an official mascot.
Document 14: Miami Maniac: The Miami Maniac, often shortened to The Maniac, is the official mascot of the University of Miami Baseball program. Although Sebastian the Ibis is the official mascot of most University of Miami sports, the Maniac is the only mascot which performs at Hurricane baseball games. Created in 1982 by visionary College Baseball Hall of Fame head coach Ron Fraser in 1982 and originally performed by John Routh, the Miami Maniac has been a constant at Mark Light Field ever since. Some believe that the mascot idea was modeled after the original Orofino High School Maniacs, from the small town of Orofino, Idaho. The Maniac mascot was used there many decades prior, and has been the target of much scrutiny due to the high school's proximity adjacent to an Idaho State mental hospital. More recently, the mascot received national attention after Idaho State officials proposed adding the Maniac mascot to an Idaho vehicle license plate.
Document 15: Colonel Reb: Colonel Reb was the mascot of Ole Miss Rebels, the collegiate athletic teams of the University of Mississippi ("Ole Miss") in Oxford, Mississippi.
