1 Playing statistics correct to the end of 2012.
Collingwood discovered McNamara, who played four seasons of NCAA Division I collegiate basketball in the US for Marist College in New York before playing one season of professional basketball in Germany for TSV Dachau Spurs.
When Collingwood gave out their jumper numbers for season 2010, McNamara requested the recently vacated number 23 (formerly worn by Anthony Rocca). Instead, McNamara was given the number 50 after Collingwood wished to keep the number 23 vacant after Rocca's departure. McNamara later said his number 50 could represent the 50 states of the United States.
McNamara is the fifth player to be born in the United States to be associated with an AFL club and the first American-born player to play for Collingwood.
In September 2012 McNamara was cut from the Collingwood list after having played 3 NAB pre-season cup matches for the club. After being delisted from Collingwood McNamara returned to his original sport, signing on to play with Sandringham Sabres in the South East Australian Basketball League. In 2012 McNamara was delisted from the Sandringham Sabres.
