I have been having a think about what side I would like England to field in ODI's and have come up with this (obviously some of these players are not on this tour, so it is a more a side for future series') :
1. A.Cook
2. R.Key
3. K.Pietersen
4. R.Bopara
5. A.Flintoff
6. P.Collingwood
7. M.Prior
8. G.Napier/D.Mascarenhas
9. S.Broad
10.G.Swann
11.S.Harmison
Now this side reverts players to playing roles they are familiar with and gives it (imo) a much more balanced look about the side.
Cook and Key are opening, Key is an innovative, clever, intelligent opener, who finds the gaps early on, will exploit powerplays, there is no need to to pick pinch hitters up there that will come off once in 10 games, but we do need quicker starts that Prior and Bell are not giving us regularly. Cook is an old fashioned style opener, but will be fully aware of his role and can play it as well as anyone.
KP is our best batsman and quite simply should have the possibility of facing a large portion of our 50 overs.
Bopara, some may prefer Shah here or Patel, has quality and has showed in 50 over cricket for Essex he can play match defining innings, however, not at number 8.
Freddie and Colly at 5 and 6 have the experience for the middle order, Colly is a decent finisher and can either re-build an innings and continue any impetus with the side.
Prior down at 7 as I don't believe his performances at the top warrant him staying there. He is neither getting us off to electric starts or playing the long innings, he's a decent bat that will be better off at 7 in my side.
At 8 I have players that KP should be more trusting with the ball, and also have great potential in the last few overs to smash it out of the ground, and quite possibly out of the town.
Broad, Swann and Harmison complete the side. Swann probably our best ODI spinner, Broad has been more than useful in ODI's recently and Harmison (in theory) offers us a wicket-taking threat.
I have eliminated players playing bits and pieces roles, batsman like Patel will contest with Bopara, Shah, Collingwood and Bell for a role he is much more accustomed to, as a batter first and foremost with an option to be given a chuck. Everyone has a defined role, currently it is similar to what England do in international football and that is select players based on their impressive form with their clubs then play them in a entirely different role for the country, not fair on the player.
Bopara and Patel are top order players and should be picked as such, or wait for an opening. Cook and Key are specialist openers, as much as I rate Bell on the Test scene, he seems confused how to play at the top in ODI's.
