No, Gaffney coached Randwick after Dywer. Gaff would be in his early 60s now and Bob in his late 60s.
Towers, the grandfather of Wallaby Pat Howard, was an interesting character. I don't know that he was ever the official coach of Randwick but he was definitely the guru that the coaches deferred to at the club.
That 1928 Tahs team I mentioned that went on tour of Britain was really the Wallabies team, and caps were awarded retrospectively to the players. This was because Australian rugby shut down at the start of WWI, unlike rugby league, and Queensland didn't start up again until the following year.
Johnny Wallace (who deserves a book on his life) was the skipper of the Tahs 1928 team and he and Towers got the team to use some of the current Randwick moves, cooked up by Wally Meagher and others. Towers played many games for the Wallabies after that and was in the NSW team (coached by Wallace) that beat the Springboks in 1937.
But I digress.
Dwyer knew nothing about back moves being a knockabout flanker who played as many games out of 1st grade as in it, but Towers passed the knowledge onto him when Dwyer became a Randwick coach. Then one day he got Dwyer to go to this Joeys warm up game against Matraville High, who ended up beating the famous rugby school.
Three brothers played for Matraville High in that game, as Towers knew, and soon Dwyer was around at their place to talk to their mum, Mrs Ella, to sign them up for the club. The Towers plan and the Ellas magic turned out to be a good mix.
Gaffney took over that legacy and now it is at Leinster - not that they wouldn't have a few moves without him with the players they have.
