Yes, as it currently stands there seems to be no other choice than to match the league filter standard in order to attract new players. For well established leagues it might work to keep well filled with being a good choice for players not being satisfied with their initial league selection and looking for a better one, but that requires well filled active tiers down to Rookie.

The reason is most likely that the league filters were fixed. I see your league isn't racing Saturday, but the filters are pre-set to daily, so only accounts setting their preferences to not race Saturday will see it now. Your other league is probably racing daily at a popular time, so doesn't have this problem.
no .... the reason is that all new managers are OBLIGED to join a league that runs every day at 7pm. therefore all other leagues are at a disadvantage. it is difficult for a new manager to immediately figure out how to find a league at the best hour for him and quit. I don't think it's that difficult to have the best options for new managers directly choose. but if i write this then i am told i am arrogant so pretend i didn't write anything.
I suppose I've to plead guilty there. I was afraid that might be the case as I remembered the new player league choice page being much more limited, and appearing to be mandatory if you don't know better, compared to the normal league search, but haven't properly checked the steps of creating a new team recently enough to be certain it's (still) the case so I worded it more carefully.
