Ian Lawson McKay (9 March 1923 – 3 April 2010) was an Australian rules footballer who played with North Adelaide in the SANFL.

[citation needed] Prior to Coleman's debut McKay had already proven himself against the "Big V", being chosen by the Victorian selectors as South Australia's best player in the 1946 clash between the states and thus being awarded the O'Halloran Trophy.

[citation needed] No less a judge than Fos Williams stated that one of the main reasons South Australia defeated Victoria in both 1951 and 1952 was McKay's brilliance in curtailing Coleman.

[citation needed] In 1976 respected journalists Mike Coward and Geoff Kingston named South Australia's greatest 40 players of the first 100 years of SANFL football.

The photograph of the mark captured McKay's dramatic leap over Norwood's Pat Hall and was reputedly distributed around the world.
