Thats a massive change in goalposts. (Deflection attempt I presume)
However, the set up of football means that teams have only set periods of opportunity to evolve.
Scott Brown was an option and one which many preferred over Langfield. That said, as the transfer window opportunities evolved, he recognised it as an area he needed to strengthen in, got in Ward and eventually Lewis.
Remember some of Browns games came at a time after Ward was recalled and we reverted to Brown.
I therefore do not understand your point on Brown and how that has anything to do with the Rogers / Woodman debate.
DM / Marshall clearly thinks that Woodman is better than Rogers.
He's brought in as cover to allow Lewis to recover.
I think the fact that Rogers has not been offered an extension to his contract which expires this summer is another indicator that the management team don't think he is good enough to eventually be in goal for Aberdeen.
I presume they think they can get better or develop Craddock more than sticking with Rogers.
