Mark Fine says it's Collingwood since 1908 and it's the fourth biggest rivalry in footy.....4. Richmond and Collingwood, 1908-present.This is another case of neighbours who couldn't get on, but in the case of the tough inner city suburbs of Collingwood and Richmond this rivalry, at least in its early days, was played out by hard men who knew how to mete out punishment.
Legend has it that Jack Dyer would not serve children who followed Collingwood in his milk bar and whilst that may be apocryphal, what is known is that Dyer would tell all Richmond players when they joined the club they automatically became haters of all things black and white.
The feuding clubs went to war in the eighties when Richmond lured young Magpie star Phillip Walsh across to Punt Road.
Walsh had just been named the League’s recruit of the year in 1984 when he signed with the Tigers. Over the next few years an inordinate number of players would move between the two clubs in a tit-for-tat war that had little to do with list management, and seemed only to fuel the flames of hatred between the two.
In recent years the rivalry has gone dormant as Richmond has fallen on lean times, but rest assured when the Pies and Tigers are once again powerhouses hostilities will be resumed.
