The problem with playing the quartet is that we don't have Gilchrist and we don't have a top order that reads Hayden, Langer, Ponting, Martyn, Clarke. Our biggest weakness is batting, especially if we have all of the fast 4 available to play.
Honestly of the 4 I don't know which one would be best to leave out. Hazlewood is the bowler who is the most proven in Australian conditions. Starc provides the most variety. Cummins is a raw, ferocious talent and Pattinson is probably more threatening than the lot of them. I'd say that Starc is the least-amazing of the four but of the four I think he is the one who definitely should play. Honestly, this headache is why the selectors have such a hard on for Agar. If they could slot Agar in at 7, Pattinson at 8, Starc 9, Cummins 10 and Hazlewood 11 you have a very strong tail. We'd then need to bat Renshaw, Warner, Smith, Handscomb, Maxwell and Nevill, which is a little light on batting-wise but it could be enough with that tail. I can't imagine any touring team would like to face the prospect of facing the quartet. The problem with this team sheet is that Lyon is by far our best spinner and has well and truly cemented his spot in the side.
Bloody good problem to have, having to decide between Marshall (Pattinson), McGrath (Hazlewood), Akram (Starc) and Ambrose (Cummins).
