IN: William Roy "Link" Lyman (November 30, 1898 - December 28, 1972), also sometimes known as Roy Lyman, was an American football player and coach. Lyman was born in Nebraska and raised in Kansas. He played college football for the Nebraska Cornhuskers football team in 1918, 1919, and 1921. He played professional football as a tackle in the National Football League (NFL) for the Canton/Cleveland Bulldogs (1922-1925), the Frankford Yellow Jackets (1925), and the Chicago Bears (1926-1928, 1930-1932, and 1933-1934).

In December 1925, Lyman joined the Chicago Bears and took part in a winter barnstorming tour that featured football player Red Grange. He joined the Bears again in the fall of 1926. The 1926 Bears team featured five players who were later inducted into the Pro Football Hall of Fame (Lyman, Paddy Driscoll, George Halas, Ed Healey, and George Trafton), posted a 12-1-3 record, and finished second in the NFL.  Lyman remained with the Bears for the 1927 and 1928 seasons. He retired after the 1928 season but returned to the Bears in the fall of 1930. The 1930 Bears compiled a 9-4-1 and finished third in the NFL. Lyman was selected as a first-team All-Pro by Collyer's Eye magazine and the Green Bay Press-Gazette.  Lyman again retired from playing football after the 1931 season. During his two retirements from the Bears, Lyman played semipro ball in Texas and worked in the ranching business.  Lyman returned to the Bears in 1933. The 1933 Bears featured six future Pro Football Hall of Fame players (Lyman, Bronko Nagurski, Red Grange, George Musso, and George Trafton), posted a 10-2-1 record, and defeated the Giants in the 1933 NFL Championship Game.  Lyman played his final year of professional football as a member of the 1934 Bears team that compiled a perfect 13-0 record in the regular season and won the NFL Western Division championship, but lost to the Giants in the 1934 NFL Championship Game. After the 1934 season, Lyman was selected as a first-team All-Pro by the United Press, Green Bay Press-Gazette, and Collyer's Eye. Bears' coach George Halas later observed that Lyman was "stronger and tougher during his last two seasons than when he first joined the team eight years earlier."

What happened after he was selected as a first-team All-Pro?

OUT: Lyman again retired from playing football after the 1931 season.

Answer the question at the end by quoting:

Stefanie Graf was born on 14 June 1969, in Mannheim, Baden-Wurttemberg, West Germany, to Heidi Schalk and Peter Graf (18 June 1938 - 30 November 2013), a car and insurance salesman. When she was nine years old her family moved to the neighbouring town of Bruhl. She has a younger brother Michael. Graf was introduced to tennis by her father, an aspiring tennis coach, who taught his three-year-old daughter how to swing a wooden racket in the family's living room.
In late 1999 and early 2000, as part of her Farewell Tour, Graf played a series of exhibition matches against former rivals in New Zealand, Japan, Spain, Germany and South Africa. She played Jelena Dokic in Christchurch, New Zealand, Amanda Coetzer in Durban, South Africa, and her former rival Arantxa Sanchez Vicario in Zaragoza, Spain. It was Graf and Sanchez Vicario's first head-to-head meeting since 1996. In February 2000, Graf played against Kimiko Date at Nagoya Rainbow Hall in Tokyo, winning in three sets. In September 2004, Graf dispatched her former doubles partner Gabriela Sabatini in straight sets, in an exhibition match played in Berlin, Germany. She was also in Berlin to host a charity gala, as well as inaugurating a tennis stadium renamed the "Steffi Graf Stadion". Proceeds from her match against Sabatini went to Graf's foundation, "Children for Tomorrow".  In July 2005, Graf competed in one tie of World Team Tennis (WTT) on the Houston Wranglers team. She was beaten in two out of three matches, with each match being one set. Graf lost her singles match to Elena Likhovtseva 5-4. She teamed with Ansley Cargill in women's doubles against Anna Kournikova and Likhovtseva but lost 5-2. She was successful, however, in the mixed doubles match. Graf completely ruled out a return to professional tennis. In October, Graf defeated Sabatini in an exhibition match in Mannheim, Germany, winning both of their sets. Like the exhibition match the previous year against Sabatini, proceeds went to "Children for Tomorrow".  In 2008 Graf lost an exhibition match against Kimiko Date at Ariake Colosseum in Tokyo. As part of the event, billed as "Dream Match 2008", she defeated Martina Navratilova in a one-set affair 8-7, with Graf winning a tiebreaker 10-5. It was the first time in 14 years Graf had played Navratilova. Graf played a singles exhibition match against Kim Clijsters and a mixed doubles exhibition alongside husband Andre Agassi against Tim Henman and Clijsters as part of a test event and celebration for the newly installed roof over Wimbledon's Centre Court in 2009. She lost a lengthy one-set singles match to Clijsters and also the mixed doubles.  In 2010, Graf participated in the WTT Smash Hits exhibition in Washington, D.C. to support the Elton John AIDS Foundation. She and Agassi, her husband, were on Team Elton John, which competed against Team Billie Jean King. Graf played in the celebrity doubles, women's doubles, and mixed doubles before straining her left calf muscle and being replaced by Anna Kournikova.

input: In early 1954, Switzer went on a blind date with Diantha (Dian) Collingwood, heiress of grain elevator empire Collingwood Grain. Collingwood had moved with her mother and sister to California in 1953 because her sister wanted to become an actress. Switzer and Collingwood got along well and married in Las Vegas three months later. In 1956, with his money running out and Diantha pregnant, his mother-in-law offered them a farm near Pretty Prairie, Kansas, west of Wichita. Their son, Justin Lance Collingwood Switzer (now Eldridge), was born that year. They divorced in 1957.  In 1987, former Our Gang co-star George "Spanky" McFarland recalled a meeting with Switzer when they spoke about the farm:  The last time I saw Carl was 1957. It was a tough time for me--and him. I was starting a tour of theme parks and county fairs in the Midwest. Carl had married this girl whose father owned a pretty good size farm near Wichita. When I came through town, he heard about it and called. He told me he was helping to run the farm, but he finally had to put a radio on the tractor while he was out there plowing. Knowing Carl, I knew that wasn't going to last. He may have come from Paris, Illinois, but he wasn't a farmer! We hadn't seen each other since we left the 'Gang.' So we had lunch. We talked about all the things you'd expect. And then I never saw him again. He looked pretty much the same. He was just Carl Switzer--kind of cocky, a little antsy--and I thought to myself he hadn't changed that much. He still talked big. He just grew up.  In January 1958 Switzer was getting into his car in front of a bar in Studio City, when a bullet smashed through the window and struck him in the upper right arm. The gunman was never caught. That December he was arrested in Sequoia National Forest for cutting down 15 pine trees; he was sentenced to a year's probation and ordered to pay a $225 fine.
