Whilst I typically agree with you, I have to say, just because she proved herself to be a talent as Roxie, doesn't mean she can play Cassie. As a friend put it "You could feel the audience's let down during 'Music and the Mirror' when she just didn't wow us." The only real thing she has over McKechnie was the back-bend, but only because it wasn't there when McKechnie did it (But when she returned it was, so there was pre-recorded drama, etc).
If any of the women get nominated it will probably be Natalie. Deidre isn't dynamic enough, and Goldwin is just too...dumb blonde with it. Honestly, I don't think it'll come away with any awards, not with "Apple Tree," "Company," "110 in the Shade," running against it.
