It’s worked for all the great sitcoms. Home ground advantage should mean having someone up in the box pressing buttons for a crowd “cheering” for points scored, chants of “parra” when it’s time to get behind the boys, and “bullshit” for bad calls.
Strangely enough, the first season the Broncos were in the comp (we lived in Qld) my old man (a saints fan) took me to a Broncos/saints game. At one point he said “Hang on, they’ve got bloody canned crowds!” Sure enough, no one around us was making a peep and the “broncos” chants were coming out of the loud speakers.
Good enough Seinfeld and the Broncos, good enough for the Mighty Eels.
