Other than Whit the Rams OL consists of a 22 year old (Brewer), three 23 year olds (Edwards, Demby, & Evans), four 24 year olds (Corbett, Noteboom, Shelton, & Allen), a 25 year old (Kolone), a 27 year old (Blythe), and a 28 year old (Havs).
With so much youth on the OL it seems to me that this group was/is probably further from their 'peak strength' than most DLs they face. If so then an offseason in the weight room should help close the gap.
I just looked at the Cowboys' starting DL: 28, 29, 30, & 32 years old
