I agree but the exact opposite is one of the reasons why we lost. Cook, Stoneman, Malan and Vince needed far more time in the middle. Although we played far too much one day cricket, we need to play one more warm up matches against top class opposition. We can't blame this on burnout as that really wasn't the issue here. Our lack of variation, wrongly balanced side, poor batsman selection (Vince is a terrible selection, look at his division 1 record), lack of conversions of 50s to 100s, top class spinner etc... There is not one single thing that is going to correct this.
We also need to stop designing our domestic season around T20 cricket, and make the focus the County game again.
The issues we face are many, and cricket itself needs to decide how it wants to develop. Currently it is very very hard to win away, until teams can stop doctoring pitches (Include in England) to suit the home teams need teams are never going to win away.
I could write thousands of words on this but I won't bore anyone!
