Faulkner or Coulter-Nile look like the left arm bowlers we have been looking for to take over from Johnson.
Bailey is one of the most overated players getting around.
Coulter-Nile is right-handed. Faulkner is okay. Would like to see his stats when he isn't playing on a seam-friendly Bellerive Oval every second week. Neither are close to Johnson.
