If Dyche left tomorrow, history would be very kind to him, he has done a great job here with everything going on.... However, from what we have seen, he has his hang ups and limitations. If this takeover involves serious people, they will look to take the club in a new direction.
He should get until the end of the season imo, but when you have a regime change, I think everything needs to be overhauled. It's no slight on the job he's done, he even made reference to such an eventuality after the Bournemouth game at the end of 22/23.
