Well, you think national and county coaches would know if a technique is good enough or not without 'taking a look'. Tbh, the game has changed now. Counties are not looking for technically sound players who play like cook/Williamson etc. They are after hales/Roy types. Money is in white ball stuff so why bother paying for a guy who can bat for 300 balls for 100-150 runs and unable to biff.
Money talks.
Obviously the genuine class players like posting, Hussey, sangakkara can change their game but we are seeing.p the majority can't and are being asked to 'do a job'. Also, it does ask questions of lvcc though if these technical issues aren't being discovered or found out.
Compton is t going to be anything other than avg but he's the best England have for top order test batting
WARNING!, too long don't read;
You make some good points, but if we are going to examine techniques and more to the point coaching techniques, is there really a set rule?.
I struggle to find examples of a perfect technique even at the top level, no two batsmen seem to have an identical posture, stance, etc and as far as coaches go just because you have the badges it doesn't mean you know what you are talking about, no matter what the level.
How did Gary Balance, Steve Smith, Shiv Chandrepal etc, etc , etc get so far with such glaringly obvious flaws? my thoughts are that they have an extremely good eye, imagine how good these players would be if they had been coached a set fast technique at a young age instead of being told 'if it's not broke don't fix it' type of coaching. I'm sure they have all tried different tweaks at some stage in their careers but because of the results orientated nature of sport they don't give the changes long enough to improve from their previous technique.
If you look at golf for an example, there is such a thing as a *perfect swing and most pros will try to emulate this but for some they just can't seem to replicate it for varying reasons and although they can have very successful careers they still won't be as consistant as the Mclroys of the golfing world. I've heard it said a few times that a golfer can't take up to three months of constant practice before a tweak can become beneficial, muscle memory I guess.
* even from the top coaches the perception of the 'perfect swing' has changed over the past 5-10 years.
I've put a lot of effort into this subject on a personal level (having only token up cricket four years ago) and although I've never been coached I've done a lot of research and there doesn't seem to be a consistant ethos from one coaching resource to another.
Ok, I think I should stop here for now, starting to bore myself, and this probably is a subject for another thread and I do apologise for the essay and poor grammar.
