We can't win the league by just having a strong first XI. Even a small injury and we're screwed.
Having cover doesn't mean having the 3/4 options they have, it just means having a couple of options for each position.
My point was that we seem to be almost pushing players out the door of they're not first pick. We signed Barisic and people were saying Wallace, John and Tavernier were out the door (John was, in this case). It was Flanagan and Barisic as first picks, and the rest could go. I'm exaggerating, but that's how it feels, at least to me.
