Kenneth William Armstrong (27 January 1936 – 5 November 2009) was an Australian rules football player, coach and commentator.
After coaching Mount Barker with some success in the late 1960s, he returned to Perth where he was a fitness trainer for the WANFL umpires in 1969 and 1970.
[1][2] After being appointed league coach in 1974 he made an immediate impact, making the grand final in 1974.
After losing the 1978 grand final, and seeing Perth fall to the lower reaches of the WANFL ladder where they have remained to this day, Armstrong briefly became director of football at Perth, but one game into the 1980 season when Peter Burton resigned[5] left to join WAFL chopping block Subiaco.
[8] After this disastrous season which had seen calls for a mid-season sacking, Armstrong was not offered another contract by the Lions[9] and left to work as a commentator for the Australian Broadcasting Corporation (ABC).
