Got to take issue with this and George Dobells article on crickinfo.
Re-read the sentence "modern Test cricketers don't play enough First Class cricket". That refers to Aussie as well as Eng,ad. Ian Chapell lamented at the end of the first days play that the pointless one day series immediately before the Ashes was poor preparation - yet the Aussies recovered well after a poor first day.
England were in Aussie a month before the first test. Whilst the warm up matches weren't that competitive, were they ever in Len Huttons day?

Who wants to give proper practice to the enemy?
It is technique that is at fault. Playing match after match doesn't help technique. As Boycott would rightly point out, it is serious practice in the nets, focusing on perfecting technical faults that is needed. Look at Simon Hughes excellent analysis of the Trott vs Bell techniques. The former is too closed and vulnerable to leg theory bowling, the latter is more open to allow the short ball past his chest. Simples.
We have Gooch, Ramps and other 'experts' out there. Trott should've been working on this months ago, but I suspect that there's been too much emphasis upon 5am runs on the beach and star jumps at the expense of proper practice. Never put Gooch in charge of anything. Ask him to swap jobs with Simon Hughes.
