If we regularly play with three CBs, you need at least 4 solid ones. Maybe the second guy off the bench can be a project, but not the first one.
Also, Long is not a likely WC starter anymore.
We had a solid 4th CB in Edwards. Not sure anyone could, or should have predicted that he'd pull a Kaku and just tell us to fuck off regardless of his contract.
I think Long is a lock for the WC. Berhalter has made getting him and Zimm minutes together one of his top priorities the last few months, time for experimenting has passed. My dad is still convinced Brooks is going to make a last second reappearance...
