Gallen at prop gives us a slightly more versatile and mobile pack, allowing Stewart at lock to inject some skill, but sacrifices an extra prop and hence affecting our ability to bash our way up the field. The backrow options are all set in stone IMO, with Galloway definitely getting one prop spot for being selected in the Australian team, and Mannah for being the best prop in the last Origin series for NSW.
The questions are who would fill the other prop vacancies - Tim Grant, Kade Snowden, Luke Douglas, Trent Merrin, Aiden Tolman, Tariq Sims and the injury prone Tom Learoyd-Lahrs are all viable options IMO. I would only play the wide-running Tariq Sims though if Gallen is at lock, otherwise we will fall into the mistake of fielding a pack that is simply too small to combat the big QLD forwards.
The bench utility spot in a bit of a question mark. Gidley has held this spot down for a while now, but personally I think he is rubbish and overrated. Greg Bird is strong, can play in the halves if needed too, and has been in good form, while Tony Williams, though a terrible selection for Australia, is versatile enough to play at wing, centre and backrow.
