Some of this England team are victims of the RWC syndrome: hanging on for one last campaign. You can't really blame players for continuing to play to earn a living, but you can blame selectors for sticking to the old players too long in the national team. It was different in 2003: that was one of the best teams of the professional era and all the players, more or less, were at their peaks, or not far from it.
I wouldn't put Jonny in the hanging on too long category because he deliberately went to play club rugby in France despite the general warning to all England qualified players that England based players would be preferred, other things being equal.
They picked him anyway. For all the players they have, they don't have a lot of good candidates for the 10 jersey as they do at scrumhalf. It's their own fault since they had Kiwis Evans, Gopperth and McAllister starting for their clubs last season. Flood will likely have the job until up and comers like his 18 y.o. Leicester team mate George Ford comes of age. The experienced alternatives all have some problem with their play, or like Hodgson or Goode, they are also past their best.
Jonno has not been innovative in bringing new players on. Ashton and Foden were selected, but a year too late. 12. Hape was a worthwhile alternative to the expansive Flutey but didn't work out in the end and that made the retention of pensioner 13. Tindall all the more important. The one shining innovation was the selection of centre M. Tuilagi. I thought that Jonno, given his innate conservatism would wait until after the RWC but he gave him a shot in the trials and he ended up being the best England back in the RWC.
In the forwards, taking serial crock 7. Moody to the RWC was a gamble that failed. 8. Easter was poor and 6. Croft was just OK. Lawes was good against Argentina in the 2nd row but was suspended during the tournament. All the others were just workmanlike except the excellent THP Cole.
I agreed with starting veteran 2. Thompson. The shorter the time that nutter Hartley can spend on the park the better. The loss of LHP Sheridan was key because it meant that Stevens, a good THP was forced to play LHP only to be found out.
Worse than the play of the individual forwards the team play, long the hallmark of England teams, was poor. They played some horrible rugby, not that Australia has been a lot better, and their behaviour was atrocious. They are home now and the RWC is better off without them.
