I do agree ASY (Angus Scott-Young) is a good captaincy choice, I just don't know that he'll have a lock on his starting spot, I think Uru isn't above him, but a few games in that could / would be a big question and you don't want your captain under selection pressure (perhaps interim captain it's more okay).
I'm torn on McReight, on one hand he's got the pedigree / background, but maybe he puts Wright's long term captaincy future under pressure (perhaps the Reds don't want that), perhaps it's too much pressure on a very young McReight... his only focus this year should be the Wallabies 7 Jersey.
JOC (James O'Connor) is a good option, he'll be in any XV he's in the leadership group, he's got a hell of a lot of experience, but his unpleasantness with the Chiefs leaves a bad taste.
Stewart is an interesting name to put forwards he'll be under a lot of selection pressure, with Paisami & Petaia both vying for those center spots. But he's got the rugby head that would make a good captain. He's probably the leader of the Reds defense last year.
