He coached the team to win six Munster titles in-a-row between 1966 and 1971. These provincial wins were converted into four All-Ireland titles in the same period. During the same period Troy was hugely involved with Cork’s under-21 hurlers. He guided them to a record four Munster and four All-Ireland titles in-a-row between 1968 and 1971.
