Question: William Tatem Tilden II (February 10, 1893 - June 5, 1953), nicknamed "Big Bill," was an American male tennis player. He is often considered one of the greatest tennis players of all time. Tilden was the World No. 1 player for six years from 1920 through 1925. He won 15 Major singles titles including ten Grand Slam events, one World Hard Court Championships and four Pro Slam tournaments.

Tilden went to the prep school Germantown Academy where he wasn't known for his tennis nor was he eventually good enough to play on his college team. The shy, self-absorbed, sometimes arrogant young man dropped out of the University of Pennsylvania and in 1910 began to practice his game against a backboard, and he also became a dedicated student of the game. The following year he won his first tournaments; the junior singles and doubles title of Germantown. He later enrolled at the Peirce School of Business. In just three years, he worked his way up the ranks. His first national title was winning the mixed doubles championships with Mary Browne in 1913 and they successfully defended the title in 1914.  From 1914 to 1917, Tilden won the Philadelphia championship. Prior to 1920, he had won a number of Canadian doubles titles, but at the U.S. National Championships in 1918 and 1919 he lost the singles final to Robert Lindley Murray and "Little Bill" Johnston, respectively in straight sets. He won six consecutive U.S. singles championships from 1920-1925 and seven in total, making him the co-record holder with Richard Sears and Bill Larned. In the winter of 1919-20, he moved to Rhode Island where, on an indoor court, he devoted himself to remodeling his relatively ineffective backhand into a much more effective one. With this change, he became the world no. 1 tennis player and the first male American to win the Wimbledon singles championship. In the mid 1920s Tilden came into conflict with the USLTA regarding alleged violations of the amateur rule, specifically relating to the monetary compensation he received for writing tennis articles.  In the late 1920s, the great French players known as the "Four Musketeers" finally wrested the Davis Cup away from Tilden and the United States, as well as his domination of the singles titles at Wimbledon and Forest Hills. Tilden had long been at odds with the rigid amateur directors of the United States Lawn Tennis Association about his income derived from newspaper articles about tennis. He won his last major championship at Wimbledon in 1930 at the age of 37, but was no longer able to win titles at will.

Problem: Jahlil Okafor (pronounced ; born December 15, 1995) is an American professional basketball player for the Brooklyn Nets of the National Basketball Association (NBA). He played his freshman season of college for the 2014-15 Duke national championship team. Okafor was heavily recruited since before high school and had been at the top of the recruiting rankings for several years. He played high school basketball in Chicago, Illinois for Whitney M. Young Magnet High School, where he earned high school national player of the year awards from McDonald's, USA Today and Parade.

Okafor's father, Chukwudi, known as Chuck, is of Nigerian Igbo and African-American descent, and his mother, Dacresha Lanett Benton, was African-American and White. As a youth, Okafor split time between his mother's home in the town of Moffett, Oklahoma and his father's home in Chicago. When he was 9 years old, his mother contracted bronchitis and died two weeks later from a collapsed lung. Okafor permanently moved in with his father to the South Side of Chicago and then to Rosemont. Okafor attended Rosemont Elementary. The adjustment was difficult because he was shy and so tall that other students thought he was put in the class for having failed. In November 2008, during seventh grade he matched his father's height of 6 feet 5 inches (1.96 m). Later the family moved to Chicago's North Side so that Okafor could attend Whitney Young High School.  As a 6-foot-7-inch (2.01 m) eighth-grader, Okafor was recruited by DePaul Blue Demons men's basketball in violation of National Collegiate Athletic Association (NCAA) recruiting rules when DePaul Athletic Director Jean Lenti Ponsetto made public comments about an offer. Initially, interim coach Tracy Webster, made an oral offer on January 30 outside the DePaul locker room at Allstate Arena. The offer was noted online by ESPNChicago.com and picked up by the press, leading to the problematic statements by Ponsetto. In February 2010, Ponsetto confirmed a statement:  This is a young guy we've been talking with for a long time, and who has been to games and we have a relationship with because his uncle works for the Rosemont Police Department...I think it's a prospect who has grown up around DePaul basketball. I think he's probably a fan and someone who has been a fan for some time, since we have played in Rosemont for the last 30 years.

What was he recruited to?

Problem: Ellington was born on April 29, 1899, to James Edward Ellington and Daisy (Kennedy) Ellington in Washington, D.C. Both his parents were pianists. Daisy primarily played parlor songs and James preferred operatic arias.

From 1936, Ellington began to make recordings with smaller groups (sextets, octets, and nonets) drawn from his then-15-man orchestra and he composed pieces intended to feature a specific instrumentalist, as with "Jeep's Blues" for Johnny Hodges, "Yearning for Love" for Lawrence Brown, "Trumpet in Spades" for Rex Stewart, "Echoes of Harlem" for Cootie Williams and "Clarinet Lament" for Barney Bigard. In 1937, Ellington returned to the Cotton Club which had relocated to the mid-town Theater District. In the summer of that year, his father died, and due to many expenses, Ellington's finances were tight, although his situation improved the following year.  After leaving agent Irving Mills, he signed on with the William Morris Agency. Mills though continued to record Ellington. After only a year, his Master and Variety labels, the small groups had recorded for the latter, collapsed in late 1937, Mills placed Ellington back on Brunswick and those small group units on Vocalion through to 1940. Well known sides continued to be recorded, "Caravan" in 1937, and "I Let a Song Go Out of My Heart" the following year.  Billy Strayhorn, originally hired as a lyricist, began his association with Ellington in 1939. Nicknamed "Swee' Pea" for his mild manner, Strayhorn soon became a vital member of the Ellington organization. Ellington showed great fondness for Strayhorn and never failed to speak glowingly of the man and their collaborative working relationship, "my right arm, my left arm, all the eyes in the back of my head, my brain waves in his head, and his in mine". Strayhorn, with his training in classical music, not only contributed his original lyrics and music, but also arranged and polished many of Ellington's works, becoming a second Ellington or "Duke's doppelganger". It was not uncommon for Strayhorn to fill in for Duke, whether in conducting or rehearsing the band, playing the piano, on stage, and in the recording studio. The 1930s ended with a very successful European tour just as World War II loomed in Europe.
