While that's not up to what we expected, it's not as bad as what I imagined. Weddle and Jefferson have improved since game 1 in coverage but where they really have not done well in is against the run, with Weddle posting a grade of 32.7 while Jefferson received a score of 38.4. This is very surprising because these two are known for being very stout against the run. Weddle I think had one missed tackle last season I believe or something of that nature. Jefferson on the other hand is known for being a top dog against the run so his grade is a surprise, I don't totally agree with it, but I don't have access to any of the past games so I can't determine anything.
That said, the duo has not been that great to start the season, the run grade from PFF is definitely encouraging as it shows that their issues are certainly fixable. I think once Weddle-Jefferson-Mosley get it together and get back to the high level of play we're accustomed to seeing from them, we're going to see this defense unfold.
I'm somewhat a critic of PFF and don't endorse their grades, but I do hold some high regard for their defensive grades.
