Vilma is definitely going to help, but with MM out for probably half the year, Thomas and Young aging another year and Harper regressing a bit last year, I think we are actually a worse defense than we were in 2007. Not to mention 2006.
I disagree strongly with that assessment. There is no chance we are, right now, with the addition of Morgan, Vilma, McCray, Gay, the expected further development of Usama Young, Roman Harper, the recovery of Brian Young (who isn't that old yet) and Charles Grant, a worse defense then in 2007.
