As others have said, it is too early, and we don't have the full squad assembled. The jury is out, but I do think that Archie is a bit stuck with the tactics which won promotion last time round. It hasn't really worked for a while, so I personally would like to see a change, or a sign of a plan B. Our best football was played with 3 at the back last year.
That said, I don't know what goes on in training. Are the players carrying out the instructions they were given ? The board are better placed than me. They backed Archie and got rid of much of the squad, so perhaps there were some bad apples and the new squad might put the master plan into action. We should know by the end of September.
