Both, I think. You can't ignore the importance of good selectors. But yes, fast pitches will surely improve our overseas record.
Gilchrist showed how to play the moving ball the other day. He constantly stayed on the backfoot, moved with the swing & then hammered the ball like he always does.
We don't have too many who play well on the backfoot. Tendulkar does, but only when he is in "that" mood. Raina showed glimpses of good backfoot play. Kaif manages it now & then. Not sure about the others...
