Lamb settled nicely into Canterbury under the coaching of Warren Ryan and playing outside Steve Mortimer. Lamb's arrival did cause initial controversy when long-serving five-eighth Garry Hughes was dropped to reserve grade in what was to be his final season. Lamb's ability to back up the ball-carrier came to the fore as he was the Sydney Premiership's joint leading tryscorer with 17. Lamb won a recall to the New South Wales State of Origin side for the 2nd match. He played well enough to be retained for the 3rd match despite the Blues losing, but withdrew due to injury. Lamb never won a junior premiership and he was closing in on one at senior level when the Bulldogs made the 1984 Grand Final against arch-rivals Parramatta Eels who were looking to win their fourth successive title. Canterbury took out the Grand Final 6–4 in a bruising game of football. Lamb was replaced with five minutes remaining due to a nasty gash above his eye.
