@bryant.coleman the possible theory is that they didn’t consider Bangladesh strong enough, and that’s why in their overconfidence they decided to not have any practice matches. Also this failure will serve them well, as it’ll help them understand where they need to be better and hopefully they’ll perform better in their upcoming matches.
If that is the actual reason, then I have to say that they made a grave mistake. Bangladesh is not considered as anywhere near the big-3, but still they can upset the best teams on their day. The only negative is that they are a bit over-dependent on some of their senior players. But the current Bangladesh is perhaps the strongest they ever had, since they received the test status from ICC in 2000. Hopefully, now they will be able to improvise further and reduce the dependence on players like Shakib al Hasan.
