Greg Brentnall played 108 games for the Bulldogs and is a member of the Bulldogs Ring of Champions.

Brentnall played Australian rules football in Riverina in the 1960s before turning down an offer to play in the VFL/AFL and switching to rugby league, taking up a contract with the Canterbury-Bankstown Bulldogs in 1972.

In 1973 he also played for Turvey Park in the Group 9 Country Rugby League competition. His ability to catch the high ball made him a valuable fullback for many rugby league representative teams, and he represented Australia.

Brentnall was a member of the inaugural New South Wales side in 1980, which saw him play on the wing, and later that year was a member of the Canterbury club's Grand Final-winning side.

In 1982, he became Canterbury's first Rothmans Medal winner and later that year was a member of the touring Kangaroo side which have since become known as The Invincibles.

Brentnall retired from playing after the 1983 NSWRL season at the age of just 26, after 108 games for the Bulldogs.

In 2004, Greg was named as a reserve in the Berries to Bulldogs 70 Year Team of Champions. On 1 April 2007, he was inducted into the Bulldogs Ring of Champions.
