I'm not sure going to 3 CBs is even viable for us now, regardless of the arguments of whether it's a better system for us or not. We surely don't have enough CBs currently available to make it a solution anyway. And if we do go back to it, we are 1 injury from being forced into going back to a back 4, but this time with no cover. We have managed to mess the defensive situation up so badly, in so many ways. From personnel decisions, to recruitment, to a fundamental lack of organisation, to what looks like zero defensive coaching, we've got the full house on how to fuck up the defence.
