The big thing I noticed re: the 7 sacks as R. Rich stated had to do with the interior of the O-line. On atleast 4 of the sacks, it would appear on a quick novice glance that either Jennings or M. Williams were playing poorly and giving up their man too quickly on circle rushes. The reality upon closer inspection though was that the interior line was getting pushed back into the area where the pocket should have formed for DB to step up into. Since that area didn't exist, the outside rushers were able to end their path in the quarterback's lap.
On the rollout sack, DB should have unloaded the ball. On one or two of the remaining sacks, it's seems that DB held on too long while waiting for a deeper route to open up.
Shelton had a missed assignment too as mentioned....
