Where are you getting the 6-8 inches from? Have you got a list of heights? Are you implying the Zimbabweans are over-age? If the Afghans are the right height for 18 then our guys are 28 by your logic. Rereading module 6 will clarify some confusing issues for you.
It's a fact that good batsmen are often shorter than normal anyway, but that trend is changing a bit.
I'm going on their facial features and overall mature look, the very things that you are stating look kosher (you like what I did there?
).
Also going on their abysmal track record of fielding over age players. To assume they've mended their ways is a stretch. Once you start cheating you don't stop until you get caught and there are repercussions greater than a laugh and a slap on the wrist.
Also going on cricinfo stats of the one guy having to be 12 years old when he started playing pro cricket. I mean right there is concrete proof there's bullshit involved and that ICC are turning a corrupted blind eye.
Also going on the fact that some of the obviously older guys they claim are 17. They're assuming someone will question the age if its 19 but not 17.
Despite all that I acknowledge the obvious hardships they've endured, probably not too different to us Zimbabweans actually- life is a struggle here too, but it should not give them a free pass. ICC need to spend money ensuring everyone complies with age requirments or it makes a mockery of it all.
They are more successful because they come from a cricket crazy country and have a player pool thousands of times bigger than ours. Our grass roots cricket has been in an extended drought
They have way more facilities that actually get used, despite probably being in disrepair. They clearly get financial support from outside of their board as well, there's no way the Afghan Board's limited budget would support that amount of cricket.
Zimbabweans need to hang their heads in shame. We neither have the will noor (see what i did there?) the ability to organise a single thing without the money and blessings of our all-powerful governing body. They engineered it and now we are dead in the water because of it. Everyone just stands there waiting for ZC to do something. Stockholm syndome at its finest. If someone tries they generally get cut off at the knees if it doesn't suit the agenda of absolute control.
