SODs is fine, we need a squad. We are about to go through another significant rebuild with a manager thats new to the country, so having an experienced player thar can cover multiple positions is valuable. He may make mistakes, but we have a squad full of players that make mistakes, it just happens to be that we all notice more when SOD is involved.
I'll preface my next comment with the fact that every goal in every game could probably be tracked down to a defender doing something wrong, and sometimes you just have to accept that making defenders make mistakes is kind of the point of attacking, but Casey has been culpable for a bunch of goals this season too.
