Career
Rosenow missed out on playing in Geelong"s 1963 premiership team despite appearing in most of their home and away fixtures but played in their losing 1967 Grand Final. He ran out as Geelong captain versus Fitzroy in the first match at Waverley Park in 1970 as it was his 100th game. Rosenow was used mostly as a ruckman and defender.
He was a strong marker of the ball and did not shy away from physical confrontation, as demonstrated by a famous incident in 1964.
The incident occurred in a game against North Melbourne at Kardinia Park when he allegedly "king-hit" North Melbourne coach Alan Killigrew in the players race which caused a brawl. Number charges were laid against him.
He joined Victorian Football Association (VFA) club Mordialloc in 1975 as captain-coach, steering them to the second division premiership two years later. He served in the role from 1975 until 1978, then returned as coach from 1983 until 1984.
He was named captain of the Mordialloc Team of the Century and positioned in the back pocket.
A police officer, Rosenow died in 1999 and was posthumously inducted into the Victoria Police sporting hall of fame.
