Loyalty is a funny thing. Everyone expects it for some reason, but in reality, there's so many factors that play a part and being a star before the competition started implies she probably could've gone to any club. If she was happy at the Bulldogs, she would've stayed. End of story.I think that in general Vescio has a good point that applies to many players, but in the case of Brennan specifically I think questioning her loyalty is fair.
Brennan was a Tier 1 player moving to another club in the same city. Due to the AFLW salary cap there is no opportunity for an increased salary. She is not moving to another club in a different location to be better placed for work or family. So then the only remaining reason is she didn't like being at the Dogs which would suggest that she is indeed disloyal to them.
Is it her right to move? Yes. But in doing so she is not being loyal to the Dogs
