This is going to be my only post on this issue (well, probably not), as it's all too painful.
Firstly, congratulations to Aus, they came with a game plan and executed it well.
Second, the series came down to one word: 'Pace'. We didn't have it, and more importantly couldn't deal with it.
Third, any comparison with 2006/7 is unrealistic. The Aus team then contained 4 genuine greats (Ponting, Gilchrist, Warne and McGrath), as well as a number of others either knocking on the door, very very good, or may become great (Hayden, Langer, Martyn, Clarke etc).
And bear in mind that in the second test in 2006/7 we declared in the first innings on 550+ with 4 wickets remaining and still contrived to lose. In other words, there was at least 2 days where we were in complete control. This time, there was only one day I can remember where we could argue it was 50:50 (the very first). Other than that, we were beaten off the park every day.
This Aus team, however, is no better than average and it is the fact Eng made them look like world beaters that is so depressing and makes this the worst performance in living memory.
Still, adds some spice for the next Ashes series.....
