Fremantle coach Justin Longmuir has warned the AFL premiership favourites are still capable of vast improvement after setting a club-record winning margin in the 124-point annihilation of North Melbourne.
The Dockers broke the game open with a nine-goal blitz in the second quarter and powered away to a 24.11 (155) to 4.7 (31) victory at Bunbury's Hands Oval on Saturday.
