I don't think there is enough evidence that Dyche has failed, definitely got some things wrong - Keane - but took over an absolute shambles and steered us to survival, then had austerity imposed upon him. It's really hard to say how well he's doing but I think a lot of slack should be cut. I really don't agree with the dinosaur label, he plays the hand he's got, and that hand is now improving slightly with the arrival of Beto, and DCL, McNeil and now Harrison returning to fitness. Not to mention Branthwaite and Tarkowski developing a solid partnership.
We're no better than a mid table side at best but I think most of us would take that at this point in time and even that will take work which requires stability.
The main problem, as always, will be what happens off the pitch, and thinking that yet another managerial change can mitigate that is madness.
