I've mentioned this in other posts. It's not as simple as Godfrey and Holgate at full back making us difficult to break down. What's making us difficult to break down is the fact that we spend 75% of the time with 10 men behind the ball. We need to find a balance where we're still solid but able to offer enough of a threat going the other way. We've struggled to do that this year, going from free scoring and leaky to solid but turgid. There is a happy medium and that's what we need to find.
It's a fair point. And it is worth noting, the discussion is really here about swapping 1 fullback in for 1 centre back at this point, and a fullback who's arguably the best in the world. There's a different discussion about right back and Coleman. It's a fair argument.
My contention with all of these things, is that balance in a back 4 is very important. We are discussing hypotheticals here, and hypothetically swapping Digne for Godfrey may not upset the balance, but also it could do. Likewise then shifting Godfrey to right back, and changing 2 positions is more likely to upset the balance. The best back 4's are rarely the best 4 defenders, but they are the players who are comfortable playing together. The whole team looks more balanced with that back 4 defensively.
On a final point, I do think there was a third phase this season. We went from free flowing, and now we are solid and turgid. There was a middle period where we were poor defensively and couldn't score at the other end. We've not improved going forwrd the other way (though look betetr with James in as any team would) but I'm not wholly convinced moving away from solidity is going to easily see us scoring lots more goals again.
There's no doubt balance is the longer term aim here. But whether it's imperaative we do it this season, when we are in the position we are, is an open question to me.
