the argument is not whether WI fielded the best team per your choice or the team that did well against certain other teams in certain other conditions. The team was chosen by your selectors assuming it was the best for the subcontinent.
Whether you agree to the team selection or not is your choice. Most of us here in BC do not ever agree with the 11 that our selectors choose, does that mean we can then down play the loses of ours?
Of the players you mentioned that WI was missing, D. Bravo is the only noteworthy omission who is no where close to what Shakib is for BD....so please don't just argue just because it helps you sleep at night.
