Problem: Background: William Miller Edwards (June 21, 1905 - June 12, 1987) was an American football player and coach. He served as the head football coach at Western Reserve University, Vanderbilt University and Wittenberg University in a career lasting more than 30 years, compiling a win-loss-tie record of 168-45-8. Edwards also coached the Detroit Lions of the National Football League (NFL) from 1941 to 1942, tallying a 4-9-1 record, and served as an assistant coach for the NFL's Cleveland Browns in the late 1940s. Raised near Massillon, Ohio, Edwards was the son of an immigrant from Wales who worked in the area's coal mines.
Context: Edwards resigned from coaching in 1969, when he was 63 years old, although he continued to work at Wittenberg as the school's athletic director. Dave Maurer, his long-time assistant, took over as the school's coach. By the end of his career, Edwards's 168-45-8 overall college record gave him the second-best winning percentage in the country among active coaches with at least 100 wins. Edwards was given a commendation by President Richard Nixon for his achievements as a coach and won a Football Writers Association of America award for contributions to the game. "His retirement is Wittenberg's loss, but more than that, it is college football's loss," University of Alabama coach Bear Bryant said at the time. Edwards retired in February 1973 after 39 years as a coach and administrator and said he would concentrate on hunting and fishing. He was inducted into the Ohio Football Coaches Association Hall of Fame in 1979, Wittenberg's Athletics Hall of Honor in 1985 and into the College Football Hall of Fame in 1986. He was also inducted into the Western Reserve Hall of Fame and the Vanderbilt Hall of Fame in 1986. Edwards died in 1987. He and his wife Dorothy had three children. The tough but compassionate approach to coaching Edwards espoused influenced many men who worked under him, including Maurer, who led Wittenberg to a 129-23-3 record between 1969 and 1983. Wittenberg's football stadium is named Edwards-Maurer Field in honor of both head coaches. The winner of the Wittenberg-Case Western Reserve football game receives the Bill Edwards Trophy. Edwards was also close with Steve Belichick, who played for him at Western Reserve and for the Detroit Lions and later served as an assistant under him at Vanderbilt and North Carolina. Belichick's son Bill was named after Edwards, who was also Bill's godfather. Bill Belichick later became an assistant coach in the NFL and is the head coach of the New England Patriots as of 2018. At what is now known as Case Western Reserve University, the football stadium, DiSanto Field, hosts its distinguished guests inside the Coach Bill Edwards President's Suite.

Problem: Background: Dwayne Michael Carter Jr. was born on September 27, 1982, and grew up in the impoverished Hollygrove neighborhood of New Orleans, Louisiana. His mother, a cook, gave birth to him when she was 19 years old. His parents divorced when he was 2, and his father permanently abandoned the family. Although Wayne and Birdman have a father-son relationship and Birdman calls Carter his son, Wayne's biological father and namesake (Dwayne Carter) is still alive.
Context: Instead of a follow-up solo album, Lil Wayne reached his audience through a plethora of mixtapes and guest appearances on a variety of pop and hip-hop singles. Of his many mixtapes, Dedication 2 and Da Drought 3 received the most media exposure and critical review. Dedication 2, released in 2006, paired Lil Wayne with DJ Drama and contained the acclaimed socially conscious track "Georgia Bush", in which Lil Wayne critiqued former US president George W. Bush's response to the effects of Hurricane Katrina on the city of New Orleans. Da Drought 3 was released the following year and was available for free legal download. It contained Lil Wayne rapping over a variety of beats from recent hits by other musicians. A number of prominent hip-hop magazines such as XXL and Vibe covered the mixtape. Christian Hoard of Rolling Stone magazine considered the mixtapes Da Drought 3 and The Drought Is Over 2 (The Carter 3 Sessions) "among the best albums of 2007." Despite no album release for two years, Lil Wayne appeared in numerous singles as a featured performer, including "Gimme That" by Chris Brown, "Make It Rain" by Fat Joe, "You" by Lloyd, and "We Takin' Over" by DJ Khaled (also featuring Akon, T.I., Rick Ross, Fat Joe, and Birdman), "Duffle Bag Boy" by Playaz Circle, "Sweetest Girl (Dollar Bill)" by Wyclef Jean (also featuring Akon), and the remix to "I'm So Hood" by DJ Khaled (also featuring T-Pain, Young Jeezy, Ludacris, Busta Rhymes, Big Boi, Fat Joe, Birdman, and Rick Ross). All these singles charted within the top 20 spots on the Billboard Hot 100, Hot Rap Tracks, and Hot R&B/Hip-Hop Songs charts. On Birdman's 2007 album 5 * Stunna, Lil Wayne appeared on the singles "100 Million" and "I Run This" among several other tracks. Wayne also appeared on tracks from albums Getback by Little Brother, American Gangster by Jay-Z, and Graduation by Kanye West and Insomniac by Enrique Iglesias. "Make it Rain", a Scott Storch production that peaked at number 13 on the Hot 100 and number two on the Hot Rap Tracks chart, was nominated for the Grammy Award for Best Rap Performance by a Duo or Group for 2008. Vibe magazine ranked a list of 77 of Lil Wayne's songs from 2007 and ranked his verse in DJ Khaled's "We Takin Over" as his best of 2007, with "Dough Is What I Got" (a freestyle over the beat of Jay-Z's "Show Me What You Got") from Da Drought 3 the second song. At the end of 2007, an MTV poll selected Lil Wayne as "Hottest MC in the Game", The New Yorker magazine ranked him "Rapper of the Year", and GQ magazine named him "Workaholic of the Year". In 2008 he was named "Best MC" by Rolling Stone. Another article, built around Lil Wayne's 2007 mixtape work, cites his creative practice as an example of post performance creative practice.
