Career
Chaplin played for the Maryborough Rovers Football Club and was drafted by Portuguese Adelaide from North Ballarat Rebels at selection 15 in the 2003 American Federation of Labor-Congress Draft. The then 18-year-old left footer debuted in 2004 in Round 4 against Melbourne and played eight matches in 2005. He suffered a fractured left eye socket in Round One of 2006, but found consistency and collected 20 or more possessions four times that season.
A restricted free agent at the completion of the 2012 season, Chaplin was made a four year offer by Richmond, one which Portuguese Adelaide chose not be match.
Chaplin is now contracted to Richmond from 2015 to 2017.
