I can talk myself into just about any choice Columbus makes at fourth, although my own preferences fall more into tiers than rankings:
My "don't bother paying attention to them, not going to make it to us" list: Celebrini, Levshunov
My "obviously this is my preference but I doubt he falls to four:" Demidov
My "Totally fine with this player" list in no particular order: Sennecke, Buium, Iginla, Silayev, Lindstrom
My "Not at all/Not at 4OA" list in no particular order: Dickinson, Yakemchuk, Parekh, Helenius
