Yeh, exactly. The plan is clear, develop the youth, play a certain way, spend big on a couple of players each year to improve the team. Sell a player occasionally for a big profit to balance the books. Well, at least that's what Leicester do and it works.
If we get rid of Smith, they will bring in another progressive manager rather than a Bruce, Allardyce type. It's not like days gone where we'd sack a manager and we'd have to start again, from the youth team set up, the backroom staff, the scouts etc. If Smith goes, who else leaves... Shakespeare? Maybe Cutler? That isn't a problem. Most managers will want at least two coaches of their own anyway.
If Smith leaves, I'd trust the board to get it right.
