Couldn't make it yesterday (which is unusual as we usually dick the opposition when I'm not at BP, Coventry this season, Peterborough last for example), but to me this sounds like a rather terrible attempt from the manager to outsmart Yeovil.
We've played well in a variety of diamond-esque formations, against better opposition, but this seemed just bloody daft.
However, the problem we've had against lower league opposition is that they pack the midfield and make it difficult for us to play, settling for a draw, or the typical spawny 0-1 win. I wouldn't be suprised if LJ set the team up to invite pressure, and hit them on the break. Cue the discussion if League 1 players are/should be intelligent/skillful enough to adapt.
