Question: Toby Gerhart held a Stanford record for most rushing yards in a season until it was broken by a player who now plays for what NFL team?
Context: All-purpose yards or all-purpose yardage is an American football and Canadian football statistical measure.  It is virtually the same as the statistic that some football leagues refer to as combined net yards.  In the game of football, progress is measured by advancing the football towards the opposing team's goal line.  Progress can be made during play by the offensive team by advancing the ball from its point of progress at the start of play known as the line of scrimmage or by the defensive team after taking possession of the football via a change of possession (such as punt, kickoff, interception, punt block, blocked kick or fumble).  When the offensive team advances the ball by rushing the football, the player who carries the ball is given credit for the difference in progress measured in rushing yards.  When the offensive team advances the ball by pass reception, the player who catches the reception is given credit for the difference in progress measured in reception yards.  Although the ball may also be advanced by penalty, these yards are not considered all-purpose yards.  Progress lost via quarterback sacks is classified variously.  Thus, all-purpose yards is a combined total of rushing yards, receiving yards, and all forms of return yards only.  Some sources do not specify which types of return yards count toward this total because the most common forms of return yards are kick and punt return yards. Yards from scrimmage is an American football and Canadian football statistical measure.  In the game of football, progress is measured by advancing the football towards the opposing team's goal line.  Progress can be made during play by the offensive team by advancing the ball from the point of progress at the start of play known as the line of scrimmage.  When the offensive team advances the ball by rushing the football, the player who carries the ball is given credit for the difference in progress measured in rushing yards.  When the offensive team advances the ball by pass reception, the player who catches the reception is given credit for the difference in progress measured in reception yards.  Although the ball may also be advanced by penalty these yards are not considered yards from scrimmage.  Progress lost via quarterback sacks are classified variously by league of play with rules having changed over time within some leagues.  The total of rushing yards and receiving yards is known as yards from scrimmage.  This definition of yardage differs from total offense which gives credit for passing yardage to the person throwing the football rather than receiving the football. Fred Wendt (born c. 1927) was an American football player.  He played college football for the UTEP Miners football team.  He led the NCAA major colleges in rushing yardage with 1,570 rushing yards in 1948.  His total of 1,570 rushing yards in 1948 broke the national collegiate rushing record of 1,281 yards set by Rudy Mobley in 1942.  Wendt's rushing record stood for 20 years until broken in 1968 by O. J. Simpson.  Wendt also broke the NCAA single-season scoring record with 152 points in 10 games, including 32 place-kicking points.  He did not play during the 1949 season due to a leg injury and was signed by the Chicago Cardinals of the National Football League in April 1950. Christian Jackson McCaffrey (born June 7, 1996) is an American football running back for the Carolina Panthers of the National Football League (NFL).  He played college football at Stanford, and was drafted by the Panthers with the eighth overall pick in the 2017 NFL Draft.  As a sophomore in 2015, McCaffrey was the AP College Football Player of the Year and the runner-up for the Heisman Trophy.  He holds the NCAA record for most all-purpose yards in a season with 3,864.  He is the son of former Stanford and NFL wide receiver Ed McCaffrey and former Stanford soccer star Lisa McCaffrey, who is the daughter of U.S. Olympian Dave Sime. Tobin Bo Gunnar Gerhart (born March 28, 1987) is an American football running back who is currently a free agent.  He was selected by the Minnesota Vikings in the second round of the 2010 NFL Draft.  He played college football for Stanford University, and was a unanimous All-American.  In 2009 Gerhart won the Doak Walker Award and was the runner-up for the 2009 Heisman Trophy.  He received 1,276 points in the Heisman voting, coming in second to Mark Ingram Jr., who received 1,304 points; the 28-point margin was the closest vote in Heisman history.  Gerhart had a breakout senior season in 2009, leading all running backs in the nation in rushing yards, touchdowns, and points scored, and setting several Pac-10 and school records.  He held the Stanford record for most rushing yards in a season (1,871) until Christian McCaffrey broke it in 2015, but still holds Cardinal records for touchdowns in a season (28), and most touchdowns in a career (44). James Abner Fordham (December 6, 1916 – April 1969) was an American football player.  He played college football for the Georgia Bulldogs football team from 1937 to 1939 and professional football in the National Football League (NFL) for the Chicago Bears from 1944 to 1945.  In 1944, he ranked among the NFL league leaders with 381 rushing yards (ninth), 5.2 rushing yards per attempt (fifth) and 38.1 rushing yards per game (tenth). John Giannantonio (born 1934) is a former American football player who set several national high school football records, many which still stand.  As a 5 ft , 137 lb sophomore at the now-defunct Netcong High School in Netcong, New Jersey in 1950, Giannantonio rushed for 4,756 yards and 41 touchdowns over the team's eight-game season.  During a game in November that season against Mountain Lakes High School he rushed for 754 yards and nine touchdowns in a 61–0 win.  His 594.5 rushing yards per game average, season rushing yards total, and single-game rushing yards against Mountain Lakes remain national high school records as of 2017. Rudolph Hamilton "Rudy" Mobley (December 8, 1921 - September 7, 2003), also known as "Little Doc", was an American football player.  He played college football for Hardin–Simmons University.  He twice led the NCAA major colleges in rushing yardage with 1,281 rushing yards in 1942 and 1,262 yards in 1946.  His total of 1,281 rushing yards in 1942 set a modern collegiate rushing record.  His football career was interrupted by military service during World War II; Mobley served from May 1943 to February 1946.  With Mobley as the leading ground-gainer and Warren B. Woodson as head coach, Hardin-Simmons compiled a perfect 11-0 record in 1946.  Mobley was drafted by the Philadelphia Eagles of the National Football League (NFL) in the 11th round of the 1945 NFL draft, and played one season for the Baltimore Colts in 1947. The 2,000-yard club is a group of seven National Football League (NFL) running backs that have rushed for 2,000 or more yards in a season.  These seven rushing seasons rank as the highest single-season rushing totals in NFL history, and reaching the 2,000-yard mark is considered a significant achievement for running backs.  No running back has yet achieved this feat twice.  The first 2,000-yard season was recorded in 1973 by Buffalo Bills running back O.J. Simpson.  He is the only player to have surpassed 2,000 yards in a 14-game season, as all others occurred in 16-game seasons; he finished the season with 2,003 rushing yards, averaging six yards per carry and an NFL-record 143.1 rushing yards per game.  Los Angeles Rams running back Eric Dickerson, who had broken the single-season rookie rushing record in 1983, recorded the second 2,000-yard season in 1984.  Dickerson rushed for 2,105 yards, the current NFL rushing record, and averaged 131.6 rushing yards per game. Harold E. "Butch" Woolfolk (born March 1, 1960) is a former American football running back and kick returner who played in college for the University of Michigan (1978–1981) and in the National Football League (NFL) for the New York Giants (1982–1984), Houston Oilers (1985–1986) and Detroit Lions (1987–1988).  Woolfolk attended Westfield Senior High School in Westfield, New Jersey.  Woolfolk led Michigan in rushing three straight years and set the school record with 3,850 rushing yards while playing for the Wolverines from 1978 to 1981.  As a sophomore in 1979, he was the Big Ten Conference scoring champion, and he went on to become a three-time first-team All-Big Ten selection.  He had his best season as a senior at Michigan, winning the 1981 Big Ten rushing title and falling just 10 yards short of Rob Lytle's single-season rushing yards record.  He was also selected in 1981 as the Most Valuable Player of both the Rose Bowl played January 1, 1981, and the Bluebonnet Bowl played December 31, 1981, as well as the Wolverines' team MVP for the season.
