Question: What is the name of the youngest coordinator in the NFL who is the head coach and general manager of the San Francisco 49ers in their 68th season in the National Football League?
Context: Kyle Michael Shanahan (born December 14, 1979) is an American football coach who is currently the head coach and offensive coordinator for the San Francisco 49ers of the National Football League (NFL).  In 2008, Shanahan, at 28 years old, became the youngest coordinator in the NFL when he was promoted by the Houston Texans.  Shanahan has also coached for the Washington Redskins, Cleveland Browns, and Atlanta Falcons.  Following the Falcons' loss to the Patriots in Super Bowl LI, Shanahan accepted the head coaching position for the 49ers.  His father, Mike, is the former head coach for the Los Angeles Raiders, Denver Broncos, and Redskins. There have been 19 head coaches in the history of the San Francisco 49ers professional football franchise.  The San Francisco 49ers franchise was formed in 1946 as a charter member of the All-America Football Conference (AAFC) before joining the National Football League (NFL) in 1950 after the AAFC merger with the NFL.  Buck Shaw became the first head coach of the 49ers in 1946, serving for nine seasons—four in the AAFC and five in the NFL.  He coached a number of future College and Pro Football Hall of Famers, such as Frankie Albert, Joe Perry, Leo Nomellini, Y. A. Tittle, Bob St. Clair and Hugh McElhenny.  In terms of tenure, Bill Walsh has coached more games (152) and more complete seasons (10) than any other head coach in 49ers franchise history.  He led the 49ers to playoff appearances in seven seasons, three of which led to the Super Bowl championship, in 1981, 1984 and 1988.  Jerry Rice, Joe Montana, Charles Haley, Ronnie Lott, Johnny Davis, Roger Craig, Fred Dean and Steve Young are among the players Walsh has coached in his career. This article is a list of seasons completed by the San Francisco 49ers, an American football franchise representing the San Francisco Bay Area.  The 49ers are members of the West division in the National Football Conference (NFC) of the National Football League (NFL).  The list documents the season-by-season records of the 49ers' franchise from to present, including postseason records, and league awards for individual players or head coaches.  The San Francisco 49ers began play in 1946 as charter members of the All-America Football Conference. The 2016 San Francisco 49ers season was the franchise's 67th season in the National Football League, the 71st overall, the third playing its home games at Levi's Stadium, and the only season under head coach Chip Kelly.  The season saw the 49ers attempting to rebound from their 5–11 record the previous year.  However, this season would prove to be even worse than the previous, as the 49ers finished 2–14, with their only wins coming against their arch-rival Los Angeles Rams.  The 49ers' record is their worst since 2004, when they also finished 2–14 (both wins were against the Arizona Cardinals).  The 49ers' 1–7 home record tied the worst home record in franchise history (not including the strike shortened 1982 season).  As a result, the 49ers fired head coach Chip Kelly and general manager Trent Baalke. The 2017 San Francisco 49ers season is the franchise's 68th season in the National Football League and their 72nd overall.  It will also be the first season under the head coach/general manager tandem of Kyle Shanahan and John Lynch.  The 49ers will look to improve on their 2–14 record from the 2016 season and attempt to clinch their first playoff berth since 2013. Dwight Edward Clark (born January 8, 1957) is a former American football wide receiver and executive.  He played for the San Francisco 49ers of the National Football League (NFL) from 1979 to 1987.  With the 49ers, Clark played on two Super Bowl championship teams.  He caught the winning touchdown pass thrown by quarterback Joe Montana in the NFC Championship Game in January 1982 against the Dallas Cowboys.  The play, immortalized as "The Catch," propelled the 49ers to their first Super Bowl championship.  Clark played college football at Clemson University before being drafted by the 49ers in the 10th round of the 1979 NFL Draft.  He served as the general manager of the 49ers in 1998 and in the same capacity with the Cleveland Browns from 1998 to 2002. The 1972 San Francisco 49ers season was the team's 23rd year with the National Football League.  The 49ers appeared in the playoffs for the third consecutive year.  After an early season injury to Quarterback John Brodie, Steve Spurrier stepped in and turned things around with brilliant performances to get the 49ers back in the playoff picture by going 5-2-1 over eight games.  In the last game of the season Brodie returned in the 4th Quarter and threw two Touchdown passes to lead the 49ers to a 20-17 victory over the Minnesota Vikings, as the 49ers won the third straight Division Title with an 8-5-1 record.  In the Divisional Playoffs at Candlestick the 49ers looked poised for a return to the NFC Championship leading the Dallas Cowboys 28-13 entering the 4th Quarter.  However, the Cowboys would score 17 points to break the hearts of San Francisco again.  This would mark the last playoff appearance for the 49ers until 1981. The San Francisco 49ers season was the franchise's 64th season in the National Football League, the 68th overall and the third under the head coach/general manager tandem of Jim Harbaugh and Trent Baalke.  This was the 49ers' final season playing their home games at Candlestick Park before moving into Levi's Stadium for the 2014 season. Arrington Jones III (born February 16, 1959) is a former American football running back who played one season with the San Francisco 49ers of the National Football League (NFL).  He was drafted by the San Francisco 49ers in the fifth round of the 1981 NFL Draft.  He played college football at Winston-Salem State University and attended John Marshall High School in Richmond, Virginia.  Jones was also a member of the Washington Federals of the United States Football League (USFL).  He was a member of the San Francisco 49ers team that won Super Bowl XVI and has been a coach on several collegiate teams. The 2011 San Francisco 49ers season was the franchise's 66th season overall, and 62nd in the National Football League (NFL).  It is the first season under head coach Jim Harbaugh and general manager Trent Baalke.  The 49ers rebounded from their disappointing 2010 season to end their streak of eight consecutive non-winning seasons.  After defeating the St. Louis Rams in week 13 and attaining a 10–2 record, the team clinched the NFC West and made their first playoff appearance since 2002 (under head coach Steve Mariucci).  The 49ers ended the regular season with a 13–3 record, their best since 1997 and earned a bye in the first round of the playoffs.  In the Divisional Playoffs they defeated the New Orleans Saints 36–32 and were in the NFC Championship for the first time since 1997 where they lost against the New York Giants 20–17 in overtime, coming just short of returning to the Super Bowl for the first time since 1994.  Despite their most successful season in years, the 49ers were 31st in the league in third down conversion percentage in the regular season (29.1) and were 17.9 percent in the playoffs.
