Pragmatically, I think losing Walker early on in the season for so long has forced a change. Previously we could be top-heavy and rely on Walker to cover. We don't have anyone who can do what he does (arguably nobody but Walker can do this).
I think Pep is trying to develop a slightly new system that allows us to be top-heavy. That's why we're seeing 3 CBs.
