There seems to be a commonly held view that the only players we must buy are those who are better than our first choicers. I think think this is to miss the point a little. We need strength in depth to cover positions, so therefore cover for Shaw at LB could conceivably not be as good as him but better than Fox. This applies to other positions in my view too. Obviously, the best scenario is to improve the first team, but this seems fairly settled, assuming we hang on to our best players.
