It all just depends on how you read into it though. Howe’s interview after Staveley left and Mitchell came in wasn’t really presenting a united front.
Your point about Mitchell bemoaning our existing strategy and apportioning blame, he’s just saying that there’s room for improvement (which there definitely is).
I do agree that maybe he shouldn’t have distanced himself from the failure of the window but at the end of the day I’d personally prefer more communication than less.
