I think it is very similar to the summer, a poor touring team getting beat by a better performing home team.
If you look at both teams, there is not much succession planning in place, or at least, there are no real performers that are banging on the door, because if there was, they'd be in already.
Look at the ages
Clarke - 32
Johnson - 32
Watson - 32
Rogers - 36
Haddin - 36
Bailey - 31
All are in their pomp, or beyond. Either way, I cannot see them improving much more, and all will tail off in the next 5 years.
Bell - 31
Carberry - 33
Pietersen - 33
Trott - 32
Prior - 31
Anderson - 31
Panesar - 31
Swann - 34
Same with England.
Got to remember that they only need to win two of the next three tests, and draw the other to retain the ashes.
