Exactly, plus the rivalries that Naracoorte have (e.g. Kybybolite is a classic but Borders as well over quite a few grand finals from the "old" days) would be lost forever. I'm not sure what the point would be. It may be the biggest town (population-wise) in that neck of the woods, but it's not like Naracoorte are dominating that league. It wouldn't be unheard of to not have a team with the league's name though ... I'm pretty sure there's no Horsham team in the Horsham & District League!p
Penola makes sense closest team was in the WBFL and KNT literally has Naracoorte in the name weird to have a league with the town name and not a Naracoorte team, Penola makes sense
