Funny you mention Bangladeshi managers...I hope sincerely that our cricketers fare better than the rest of the Bangladeshi "workforce". I think if you hired a couple of low-lifes from the streets of Compton and Watts with no high school diplomas they'd do better than Bangladeshi managers.
Cricketing wise, the BCB needs to realize the problem, and I'm sure they don't because they're all corrupt politicians and come form non-cricketing backgrounds. Lack of talent is not the problem in BD...talent cultivation is. Sri Lanka have clearly done more with less.
I drop knowledge so heavy it leaves the world unbalanced, exterminating the spiritual force of all that challenge, I'm the lyrical apocalypse that crumbles the granite, replacing you as the dominant species on the planet.
