It's all just media narrative really. They'd hate to give credit to Dyche as a manager without it being some backhanded compliment as if he's some football dinosaur. If anyone has actually heard him speak on tactics or just in general you can see what an intelligent, insightful and articulate man he is. Was chatting to someone the other week and they thought I was mad to act like he was a "footballing" manager, classic case of a book being judged by it's cover and quite frankly I'm rather happy about it because some of the more "fashionable" teams that have sacked managers absolutely missed a trick in not getting him in earlier than us.
I would say out of all the managers that have been sacked and replaced this season only ourselves and Villa with Emery have gotten huge upgrades, everyone else has swapped managers for slight upgrades, or even downgrades in the case of Southampton and most likely Palace along with Leicester and West Ham when they inevitably sack their managers too.
