David Warner's form over the last 2 years has been very questionable, but there is no doubt that his retirement will leave a massive hole in this Australian team. Currently, there are 4 contenders to replace him at the top.

In my opinion, Cameron Bancroft must be selected for Adelaide. If Cameron Green is chosen as an opener, it implies that Sheffield Shield cricket means absolutely nothing and indicates a broken system. Whoever they pick, Cricket Australia needs to stick with this player for at least 12 months and back them against the West Indies and India at home, as well as New Zealand away.
