Background: Vladimir Tismaneanu (Romanian pronunciation: [vladi'mir tism@'neanu]; born July 4, 1951) is a Romanian and American political scientist, political analyst, sociologist, and professor at the University of Maryland, College Park. A specialist in political systems and comparative politics, he is director of the University of Maryland's Center for the Study of Post-Communist Societies, having served as chairman of the editorial committee (2004-2008) and editor (1998-2004) of the East European Politics and Societies academic review. Over the years, Tismaneanu has been a contributor to several periodicals, including Studia Politica, Journal of Democracy, Sfera Politicii, Revista 22, Evenimentul Zilei, Idei in Dialog and Cotidianul. He has also worked with the international radio stations Radio Free Europe and Deutsche Welle, and authored programs for the Romanian Television Company.
Context: Some who oppose or criticize Tismaneanu's appointment to head the Presidential Commission, his selection of other commission members, or the conclusions in the commission's final report, have drawn attention to several texts he authored in Romania, which they perceive as being Marxist-Leninist in content, and his activities inside the Union of Communist Youth. Among the critics of Tismaneanu's early activities was philosopher Gabriel Liiceanu, who stated that they were incompatible with the moral status required from a leader of the Commission. However, Liiceanu endorsed the incrimination of communist regime and eventually the report itself.  After the presentation of the Final Report and the official condemnation of the communist regime by President Traian Basescu in a joint session of the Romanian Parliament, Liiceanu openly expressed his support for Vladimir Tismaneanu and endorsed the Presidential Commission for the Analysis of the Communist Dictatorship in Romania. In November 2007, Liiceanu's publishing house, Humanitas, published in volume format the Final Report. Furthermore, Liiceanu, in the homage to Tismaneanu, when the latter was granted the award of the Group for Social Dialogue (January 2008), openly retracted his initial statements about Tismaneanu's academic and moral stature: "Vladimir Tismaneanu was the perfect person for completing the task of coordinating the Commission, considering that those who spoke after being exposed to this ideology explained it best. Vladimir Tismaneanu, besides owning such insider knowledge on what is communism at multiple levels, he then had an ideal competence, acquired and validated within the American academic environment, in order to be able to study this subject with both familiarity and distance." Liiceanu concluded: "He is the most qualified intellectual in the world for analyzing Romanian communism. His book Stalinism for All Seasons is the classical study in the field."  Early criticism of Tismaneanu based on allegations of communism was also voiced by writer Sorin Lavric. The author revised his stance soon afterward and, in four separate articles, gave his endorsement to both the Final Report and Vladimir Tismaneanu's later publications.

Problem: Background: Daniel Lee Dierdorf (born June 29, 1949) is a former American football offensive lineman and current sportscaster. A native of Canton, Ohio, Dierdorf played college football for the University of Michigan from 1968 to 1970 and was selected as a consensus first-team All-American in 1970 and a first-team All-Big Ten Conference player in 1969 and 1970. He was inducted into the University of Michigan Athletic Hall of Honor in 1996 and the College Football Hall of Fame in 2000. Dierdorf played professional football in National Football League (NFL) with the St. Louis Cardinals for 13 seasons from 1971 to 1983.
Context: On September 9, 1979, Dierforf sustained torn ligaments in his left knee during an extra point attempt in the second quarter of the second game of the season against the New York Giants. After the game, Dierdorf said, "The knee was completely out of the socket. It moved a couple of inches off to the side. My leg was all twisted around and my foot was pointing in the wrong direction. It was painful. Very painful." Dierdorf was carried off the field on a stretcher, underwent knee surgery, and missed the remainder of the 1979 season.  Dierdorf returned to the Cardinals in 1980, starting all 16 games for the team at right tackle in both the 1980 and 1981 seasons. In 1980, he was selected to play in the Pro Bowl and was selected as a first-team All-NFL player by the NEA. In 1982, Dierdorf moved to center and was the starter at that position for all nine games in a strike-shortened season.  In 1983, Dierdorf returned to his right tackle position and appeared in seven games, only four as a starter. On October 11, 1983, after the Cardinals began the season with a 1-5 record, Dierdorf announced that he would retire at the end of the 1983 season. At the press conference announcing his retirement, Dierdorf said, "This was an easy decision for me to make. . . . Physically, I just can't play the type of game I want to." He added: "Ninety-five percent of me is sad that I'm retiring, but my knees are very, very happy."
