Firstly, foreseeable future =/= forever.
Leeds are not a well ran club, so the point about not having to spend the world (relatively) and be well ran on and off the pitch and sneaking up does not apply here.
Leeds need a period of stability, I genuinely believe that Redfearn would have done what Gray did for Wednesday, albeit at Leeds. Which is to bring a period of stability to the team while off the pitch is sorted.
You cite Wednesday as being a case in point this season of being ambitious, but that comes with major investment on and off the pitch, a new manager with ambition, but all of which was built on a period of ~18~ months of stability, not pushing for promotion, not getting relegated, settling for being in the division basically.
Leeds need stability on the pitch, they need it off the pitch which will not happen until Cellino leaves. Then a 'good' owner(s) would come in, invest in the team and club and encourage ambition.
Leeds feel like a sinking ship, they need to stabilise, plug the holes and tread water until they can repair and move forward.
