At club level he won eight senior football championship medals for St John's, as well as two senior hurling championship medals. He also won an Ulster club hurling championship medal with St John's. During the 1970s, he played with
Tarbert in Kerry for a spell while he worked in the ESB station there. In 1980, he left his native county to settle in
Limerick, where he played with Mungret. McCallin became a regular on the
Limerick county football team and played one game for Limerick in the Oireachtas Cup against
Kilkenny. In 1987, McCallin returned to his native Antrim, choosing to live in
Cushendall in the
Glens of Antrim. He played hurling with Cushendall and football with Glenravel and went on to represent Antrim masters in 1999. He has since retired from both football and hurling but is managing the senior football team in his St John's for the 2008 season.
Management While McCallin was still in his twenties he took up his first management role. As a manager, he won three consecutive titles with county minors with St John's in 1972, 1973 and 1974. With this experience behind him, he became the manager of the Antrim minor team between 1977 and 1980 until he left his native county to settle in
Limerick. In 1984, he became the manager of the Limerick senior football team; this proved to be an unsuccessful period in his career. He returned to Antrim in the late 1980s and has since managed the St. John's senior football team. He also plays golf off a handicap of 6. ==References==
