In our series of depth chart reviews we now come to the backbone of the defense, the center backs. This was an area of concern for the Philadelphia Union last year, which is why they had to move Maurice Edu from central defense as an emergency defender.
The center back position is a thin one for the Philadelphia Union. It is also, one full of unproven players. Currently, there are three center backs on the roster not counting Maurice Edu (who is an emergency option), and between them they have 21 games of MLS experience (all going to Richie Marquez).
