Has any team ever finished the entire VFL or AFL year undefeated?

essondon was extremely close in 200 where thya won 21 out of 22 premiership games (a record). my i also note that it is impossible for a team to win every game of the seasonm including finals because u wuold go undefeated 22 games and be topof ladder . will qualifyinf, win preliminary and hten win grand final but there are the elimination and semi finals whicxh aer also played . just thought id add that in :)
