Angus McAlpine's soccer career began in Scotland when he attended Possil Secondary School in his hometown of Glasgow. From 1950 to 1952, McAlpine played as a Junior Professional in the Western League before serving briefly in the military. While serving, he played for both the Scots Guard and Royal Signal Regiments and was selected to play with the Brigade of Guards team.
After his time in the military, McAlpine played in several Scottish first and second division teams until 1968 when he completed SFA Coaching School. This is also the year that McAlpine relocated from Scotland to Atlanta and was selected to be a part of the first GSSA All Star Team just two years later. From 1971 to 1976, he served as Georgia Soccer's first Director of Coaching and sailed through the USSF coaching courses to receive his C, B and A licenses by 1973. During this time, he also coached within Georgia Soccer's Amateur League and coached the Atlanta Metros in an undefeated season.
In 1975 and 1976, McAlpine served as the USSF Southern Region Head Coach. During his reign, he led the US National Youth Team on its first tour of Germany and to the Junior World Cup tournament in Puerto Rico. In 1979, he developed a complete coaching curriculum that was used for many years by the USSF.
From 1980 to 1981, McAlpine acted as the NASL's Director of Player Development. He guided the U20 and U16 USSF National Team to World Cup play in Mexico in 1985 and China in 1987. The same year they played in China, McAlpine also served as the Head Coach of the US Army Team. During the year in between coaching in Mexico and China, he was named National Elite Staff Coach by the USSF as well.
From 1995 to 2001, McAlpine coached the Chattanooga Express and Atlanta Ruckus, served as Assistant to the USSF Under 14 National Team in both US and Mexico competitions and served as Assistant Coach of the US Under 14 National Team.
The list of McAlpine's accomplishments well extends this, but through his time with Georgia Soccer he has made quite the impact as both a coach and as a technical advisor. In 2002, he was inducted into the Georgia Soccer Hall of Fame.
