I suspect this is a mindset from the NFL or something. As soon as NFL teams cant make the playoffs they go on holiday or something?
Im almost certain every Everton fan wants, bar probably you, wants us to win every point on offer from now till May, yes the season is effectively over, with nothing meaningful to play for, but 5th is still 5th and Europa is still Europa. Europa and 5th compared to nothing and 12th is worth about 40m to the club, cant think of a better way to prepare for next season than that personally.
But im curious how you would "prepare for next season", I assume it involves playing a load of substandard players in some shape or form.
