Richard Copeland Slocum is the winningest coach in Texas A&M University history. His career record is 123-47-2 in 14 years.
 
Better known as R.C. Slocum, R.C. was raised in Orange, Texas, and graduated from Stark High School in 1963. Slocum attended college at McNeese State University, where he was a four-year letterman and set school records for receiving as an end. He received his undergraduate degree and later a Masters of Education Administration. 
 
In 1968 Lake Charles High School became the first stop in Slocum's coaching career. From there, he went to Kansas State University. He was hired as an offensive assistant at Texas A&M in 1972. 
 
In 1981 Slocum helped lead the University of Southern California to the Fiesta Bowl. A year later, he returned to Texas A&M as a defensive coordinator. In 1985 he was promoted to assistant head coach, and in December 1988 was promoted to head coach. The Aggies led the Southwestern Conference in defense and won the first of three straight championships, which earned their defense the nickname of "the Wrecking Crew."
 
Slocum won six championships as head coach; three Southwest Conference titles, two Big 12 South Division titles, the 1998 Big 12 Conference Championship, and 11 bowl games, including the Big 12 title in 1998 and two Big 12 South Championships in 1997 and 1998.  With Slocum as the head coach, the Aggies became the first school in Southwest Conference history to post three consecutive perfect conference seasons and went four straight seasons without a conference loss. Slocum reached 100 wins faster than any other active coach at the time. He has the best winning percentage in SWC history, one spot ahead of the legendary coach Darrell Royal who is number 2. Slocum helped make A&M's Kyle Field one of the most challenging places for opponents to play, losing only 12 games at home in 14 years.  At one point, A&M held the longest home winning streak in the nation, finally losing in 1989 and not again until late 1995. In the 1990s, A&M lost only four times at Kyle Field. Slocum was named SWC Coach of the Year three times during his tenure as head coach. Over 50 A&M players were drafted into the NFL during Slocum's tenure. On ten occasions, the Aggies finished ranked in the AP Top 25 and three times in the Top Ten.  
 
At the close of the Southwest Conference era, Slocum's winning percentage of .865 (44-6-2) was the best in league history.
 
At one time, Slocum was involved in many charities, including the Children's Miracle Network, the Houston Livestock Show and Rodeo, and the Special Olympics. Retiring from coaching in 2002, Slocum has since served as a Special Advisor to the President of Texas A&M. In 2012, Slocum was inducted into the College Football Hall of Fame.
 
His oldest son, Shawn, was an Assistant Coach under him at Texas A&M and has been the special team's coach for the Arizona State Sun Devils since 2015.
