Most clubs certainly below the Premier League are running at a loss, most of them at a big loss that they wouldn't be able to trade in any other industry.
They have 3/4 managers per season and with that 3 or 4 squads(as us last time in Division 2)the owners then walk away and you end up in an Oldham/Bury/S****horpe situation .. and almost us.
If you limit how many managers/players you can have a season surely it makes football clubs more sustainable and levels the playing field
