Are injuries really to blame or are Beckett and Lackey?

A Red Sox Fan From Pinstripe Territory points out that combined, Lackey and Beckett are 5-12 since August 1. It's starting to seem as if the offensive injuries did not sink the team as much as unreliable pitching from those two starters. We still don't seem to have an explanation about what's wrong with those two expen$ive players, except that they seem to not be able to locate their pitches these days. 2011 will also depend heavily on those two.
