Why don’t we have a knockout cup competition like soccer?

Everyone is up in arms about opening round and the wildcards for finals, which I’m totally against. However, if the AFL wanted to generate extra excitement I think it could be in a knockout style competition that included AFL, VFL, SANFL, WAFL clubs etc. In England these knockout tournaments generate extra excitement especially for clubs that are not in the running to win the league they’re in, so there’s something else to play for halfway through the season. It would be a great way to see AFL clubs play the state league clubs, right now I honestly don’t think Essendon would have a hope against the best VFL sides lol. So it could be quite competitive.
