You could probably argue that on form it should be Romaniuk but I imagine it’ll be one of Tinao, Predebon or McEwen making way, assuming (and hoping) Butler is back. If it's one of the middles Tinao seems like the obvious answer but Predebon was dropped over her earlier in the year, and Tinao hasn’t missed a game since. Get a bit more mobility in attack from Tinao, more just overwhelming size from Predebon. Both can be struggle laterally in defence at times.
McEwen’s drawback is just inexperience. If she was nervous on debut it didn’t show, but it might be a different story marking up against Amber Hall in a sudden death final.
