Problem is that with increased focus on junior T20 the development of bowlers is restricted too. The "give everyone a go" issue means everyone bar the keeper gets 2 overs each, and half the kids dont get a bat.
My son (now 20) is a bowler. Nothing special, he went through the district junior rep program up to Under 16's but mostly in the 2nd XI. As more T20 rolled out he enjoyed his junior cricket less and less - so at 14 or 15 he started playing mens afternoon astroturf cricket where at least he would get an opening spell of 5 or 6 overs and then come back later and never went back to juniors.
The give everyone a go philosophy is being unfairly blamed for a lot of issues I reckon.
I am 35 and came through ‘you get 2 (later four) overs to bat’/bowl’ cricket in the lower primary ages (under 8s and 10s from memory) and I know for a fact it was happening before I was playing. And the cricketers of those generations never had such issues in batting time or showing patience.
By the time you reach the teen years, yeah, you should have learned to cope with the immediacy of being dismissed - you only get one chance - and of being in the field for 30-40 overs and not getting a bowl. If the 5-6 years of development you receive at that point aren’t enough to teach you to value your wicket, you’re probably never going to learn the skill.
There are two things which have a role to play, IMO. One is coaching at the youngest levels. In the age groups where you can’t be dismissed (my sons play in them at the moment) I see a lot of coaches telling their players to have a swing at basically everything because they’re going to face their allotment regardless. I know with my boys I tell them to block anything on the stumps - the only free swings I encourage are at balls down the leg side.
The other, whether people think it’s unfairly blamed or not, is the Big Bash.
Look at the IPL. There are what, 8-9 franchises or something. In any given side there are 3-4 internationals from other countries. There are literally a few dozen first class sides in India. So the chances of a Fc cricketer getting into the ipl are mathematically small, and while it is obviously a huge goal for a any Indian player, it’s very very tough to crack so as a result the Ranji Trophy remains a very lofty and more realistic goal for a huge majority of their players
In Australia we’ve got 6 FC sides worth of players, and much less overseas players, vying for spots in the Big Bash. Financially it is the biggest lure for our regular domestic players and they can almost ALL get a game. Therefore it makes sense for them to Tailor their games to the format and focus on it.
If a young batsman at the start of the season has to choose between 2 hours of blocking work in the nets, and 2 hours of fine tuning that can help him get a Big Bash contract hitting sixes, what’s he going to choose?
