It is insane, without wishing to defend them maybe that batshit crazy policy was imposed to cover situations where we had the windfall sale of a particularly valuable player like Wharton or Szmodics with the thinking being the budget for the following season could be upped slightly.
It's a bit different when at least half the starting X1 are just walking out for relatively modest fees. There has at least been some acknowledgement now that we need a RW and replacements for anyone else who leaves albeit we're still waiting and anyone who comes in will probably be a lot cheaper and theoretically inferior.
