I want to have a discussion regarding Zakuani and his impact on the team. Does the team play worse with him back in the lineup? Or perhaps the team plays better with Caskey or whoever else has played out on the left during the season?

I do not have any stats or play breakdowns, but I just noticed that around the time Zak appeared in the starting lineup, the Sounders cooled off. Perhaps it has nothing to do with him at all, but I wonder...

Any thoughts?
