[8] Former Lions captain Willie John McBride stated that Millar had given "his whole life to the game".

[12] A highly technical prop, he focused on the set-piece and could play on either side of the scrum at the highest level.

[13] Millar played 39 games for the British and Irish Lions, including 9 internationals, on 3 tours.

[15] Terry O’Connor (rugby writer) said: “In my view Millar has always been under-rated as a coach and overshadowed by Carwyn James who was in charge of the 1971 team.

James was a visionary about back play but accepted that his forward knowledge at Test level was limited.

He presided over a governance restructure and new strategic plan for the IRB, and was influential in the continued lobbying for Rugby sevens inclusion in the Summer Olympics.

[25] Millar was awarded the Honorary Degree of Doctor of Science by the University of Ulster in 1992,[26] and was inducted into the International Rugby Hall of Fame in 2003.

[26] On 12 December 2007, Millar was appointed to the Légion d'honneur, France's highest decoration, at a ceremony in Ballymena Rugby Club, by Bernard Lapasset, his successor as IRB Chairman.
