Well, we'll have to agree to disagree there. Page's judgement was awful (as proven by the stats) and Edinburgh's doesn't seem to be much better so far.
I think you have missed the point a little. We simply cannot prove that we would have done better last season had MacDonald played instead of Nyatanga, Byrom instead of Taylor and D'ath instead of P Anderson. The only way we will ever know if Page's judgement was flawed is if the players he ignored / froze out / moved on come back up to at least League One level and perform.
He was a poor manager, his recruitment was poor - we can objectively prove that with the stats. We can't do that with these players as they have no stats at that level to back that up, we're just guessing
