Roy Allen Williams (born August 1, 1950) is an American basketball coach, currently the head coach of the men's basketball team at the University of North Carolina. After averaging nearly an 80% win percentage in 15 seasons at the University of Kansas, he became the eighteenth head coach at North Carolina when he replaced Matt Doherty in 2003. He is second all-time for most wins at Kansas behind Phog Allen and at North Carolina behind his mentor Dean Smith. Additionally, he is sixth all-time in the NCAA for winning percentage. Williams has taken his teams to seven Final Fours in his careers at Kansas and North Carolina (fourth all-time in NCAA history) and is the only coach in NCAA history to have led two different programs to at least three Final Fours each. From 1990 to 2009, Williams led his teams at Kansas and North Carolina to 20 consecutive NCAA Tournament appearances (second all-time) and earned at least one victory in each appearance, achieving the all-time record for most consecutive NCAA Tournament appearances with a win. These streaks both ended in the 2009–10 season as UNC failed to receive a bid to the NCAA Tournament. He earned his 400th win in January 2003, when Kansas beat the Wyoming Cowboys. Williams won his 500th career game against High Point University on December 9, 2006 in Chapel Hill. On November 29, 2009, Williams earned his 600th career victory by defeating the University of Nevada. Williams became only the 33rd coach in Division I Men's Basketball history, as well as the third-fastest, to achieve at least 600 career wins. On April 4, 2005, Williams shed his title as "the most successful coach to never have won an NCAA ring" as his Tar Heels defeated the University of Illinois in the 2005 NCAA Championship game. He would again lead them to victory four years later, defeating the Michigan State Spartans in the 2009 NCAA Championship game on April 6, 2009. Williams is the fourth active coach, and thirteenth overall, to win multiple National Championships. In 2007, Williams was inducted into the Basketball Hall of Fame. He has coached his teams to 30 or more wins in 10 of his 24 years as head coach (Kansas and North Carolina).

James Joseph Dykes (November 10, 1896 – June 15, 1976) was an American third and second baseman, manager and coach in Major League Baseball who played for the Philadelphia Athletics and Chicago White Sox from 1918 to 1939. He batted over .300 five times and led the American League in assists once at second base and twice at third base, ending his career sixth in AL history in games at third base (1,253), and seventh in putouts (1,361), assists (2,403), total chances (3,952) and double plays (199). When he retired, he ranked eighth in AL history in games played (2,282), and ninth in at bats (8,046). He holds the Athletics franchise record for career doubles (365), and formerly held team marks for career games and at bats. He went on to become the winningest manager in White Sox history with 899 victories over 13 seasons, though his teams never finished above third place; he later became the first manager in history to win 1,000 games without capturing a league pennant.

Born in Philadelphia, Pennsylvania, Dykes played for three local teams at age 16 in 1913. The first was "his father's Penn Street Boys Club"; the second one paid 50 cents a game plus carfare (to Ardmore on the Main Line); the third paid $1 a game. By 19 he played in the Delaware County League, which the major leagues declared an outlaw league a few years later, for infringing their control of the professional sport.
