Michael Vaughan has written a recent article criticising the county system for not producing enough Test cricketers and pointing out the number of teams that get skittled out and solely blaming pitch preparation and the desire for 'result pitches'.
This is the same man who pushes The Hundred and Twenty20 cricket and criticises 'traditionalists' who prefer the longer formats. Yes, preparing 'result pitches' has always been a thing. But the new reasons more teams might get skittled in recent years is because the schedule pushes the championship games to April, May and September while the T20 and now The Hundred get June, July and August in the hope of getting better weather and bigger crowds. So the weather is more conducive to bowling when the championship is played.
There's also the fact that, with all the money going into the T20, IPL, and The Hundred (which Vaughan loves), there's far more incentive for players to produce a game conducive to those formats (an attacking game with the bat - and priority on pace off the ball when bowling) to make sure they're purchased for those - rather than becoming a Michael Atherton, Haseeb Hameed, Shivnarine Chanderpaul types who sell their wicket high in the longer formats but wouldn't garner a big price in the competitions where all the money is.
It's really sneaky and hypocritical of Vaughan to try and focus solely on the wicket preparing side to put the blame on the counties, and deflect blame from the development of, and priority on, the money making one day competitions that's pushed the County Championship and 50 over competitions down the list of priorities in terms of schedules and player development.
