But thats not Bangladeshs fault is it? Every Bangladeshis admits they were given test cricket miles too early. The standard of Bangladesh in 1999 would be the equivalent to Namibia today, they were hopeless but due to politics and a massive fanbasde they were given the holy grail.
In the last 7 or so years they've made good progress, 2007 WC they beat 2 good sides, 2011 they beat England and in 2015 they made the knock outs and very nearly beat one of the finalists. They've made the next step up now and IMO are a good ODI and t20 side. Test they still have some way to go I agree.
As for Ireland, simple fact is Ireland if given all the support we want could potentially after several years be like Zimbabwe from the late 90's, decent side with great work ethic who fight hard. Thats about it.
Bangladehs by virtue of their massive population could well be a force in cricket in a couple decades and could well challenge for world cups. Thats why they were given test cricket anyway, it sure as hell wasnt down to quality.
But, that aside, they're a good limited overs team who are a bit weak mentally, definitely not minnows IMO.
