4. R.C Slocum (1989-2002)
Slocum’s first and only head coaching job came at Texas A&M. He began his career as a high school coach at Lake Travis and slowly worked his way up the ranks via stops at Kansas State, USC and Texas A&M. Slocum was the defensive coordinator for the Aggies for seven seasons before being named the head coach in December of 1988.
He led the Aggie program for 14 seasons, racking up 123 wins. That still stands as the most victories by any Texas A&M coach all time. His .721 winning percentage ranks second among Aggie coaches who coached at least 50 games.
In 1992 the Aggies posted a perfect 12-0 regular season, including a 34-13 victory over the Longhorns in Austin. That Texas A&M team became the first undefeated team to be invited to the Cotton Bowl.
The knock on R.C. will always be his bowl record, 3-8. He had five 10-win or better seasons, including a four-year stretch from 1991 to 1994 in which the Aggies went 42-5-1. That included three trips to the Cotton Bowl, all losses.
When you consider the nine years that followed Slocum his value grows. The Aggies replaced R.C. with Dennis Franchione and then Mike Sherman. Neither coach won a bowl game. Slocum’s three wins might not have been enough, but they were certainly better than zero.
