You are spot on, I think part of the problem with Berry holding onto it too long is to do with her passing. She only gets it right 50% of the time and I think she is conscious of this now as well. We need to remember this is only her second year of playing fullback and she hasn't quite developed the necessary ball skills that she needs. If she can work on this and add that dimension to her game, she will be unstoppable.
You are right though that they don't use her correctly in attack. More often than not it doesn't really seem like they actually have a gameplan. It is just hit it up, get it to Berry, if she can't do anything kick. When we do score it's either off a kick, created by Berry or a bit of individual brilliance mixed in with some bad defence.
Is the coaching structure the same as the mens where there is an attack & defence AC under the HC, or is Sowie doing it all? Does anyone know.
