Ouach! That's harsh. I agree her reception is sometime shaky and her back row defense is weak. But I wouldn't say she's not a NT material.
You've just assumed her reception is shaky and her defense is bad also. Her attack is not good either. What is she good at then?
I do like Amanda, I am happy for her growth in the past two seasons playing is our Superliga, but she should not be starter in Brazil NT. It's quite different level that I am pretty sure she does not belong (at least yet).
