Why not just go on a steady ship and introduce players as the form demands it.
Everybody knows why we have had a bad year or so and that was the loss of 3 players for a year. One of them happened to be the Captain and our best player(also number 1 batsman in the world at the time) and the other 2 are very good opening batsmen. Warner is obviously a danger to opposition sides and that is why he was being targeted on the fateful tour.
