The only argument in my eyes for him staying is that we've missed the window to change manager and it would take way too long for:
1. The board to dither about and appoint another manager
2. Said manager to implement his style with players he didn't bring in.
The time to do it was straight after last season, Bournemouth did it despite O'Neil doing a better job than Dyche.
I just find him dead annoying and if you're gonna play pragmatic footy, you better get results and he doesn't.
But I do agree with what you're saying.
