It's a long long time since AWB was close to being solid at rb.
Not sure why you're referring to Antony as some sort of golden child considering the amount of times he's been overlooked and subbed, or why you're pretending Amad to be some obvious answer to our problems.
The point is quite simple, every time you stick Dalot on the left back with AWB on the right you get the exact same comments on how it's absolute madness, how they should swap position, ETH is a moron for not seeing it. It's always easy and simple.
But it's not that simple, it's not an obvious flaw in decision making. AWB isn't a close to being a good rb, Dalot is a much better right back, so instead of a half cooked solution where both players are underperforming you hope that the team will benefit from having Dalot, who is overall a better player, in his preferred position, both from an attacking and defensive perspective.
