I keep coming back to this post, because it's happened since Glenn came back into the side, and probably before, but I haven't looked for it. Every time they send the decoy on the angle he goes for it and we're left a player or three short out wide. Croft is still garbage but the overlap has already happened and it's a formality from there.
Herbie had a bad game but we've seen him defend far better than that, which means it's either an outlier, or the problems start back infield. My money's on the latter
