Well in his only full season here so far the team improved by 12 points whilst the club turned a transfer profit, so he must have done something.
Quite simply if he was genuinely doing all the stuff people are accusing him of we wouldn’t still be in the league.
Its the most ruthless cut throat league in the world with top managers and top players and people are seriously pretending that you can get 48 points against these other teams and managers by hoofing and looking for flick ons to no one. As if these managers would genuinely lose games against a team whose only method of playing was that.
The other thing is that managers in this league catch on to predictability, it’s why some managers have a decent half season and then next season are relegated or fired. Managers adapt and suss out tactics. If Dyche is still getting results 22 months later then the only logical conclusions are he either is varying his tactics or his plan A is so effective that some prem managers even 22 months can’t counter it.
For those who say he hasn’t demonstrated an improvement. If you could show a table of all Pl teams points per net pound spent improvement during the time Dyche has been here where do we think he would be? Then look at where the club was when he arrived and the squad we had and ask could we really have asked more of him than that?
