Collingwood has won over 15 premierships and Jock McHale was in charge for eight of them, including the four consecutive flags from 1927-1930, a feat no club has ever matched. Author Glenn McFarlane examines the life and times of McHale, his impact on Collingwood and the game and what drove him during the 38 years he was in charge of the Magpies, a record for coaching tenure in football that is yet to be broken.
