The issue is, the O line. It could not block period. Dbrick, was just as bad as hunter. Dbrick is a terrible run blocker as is hunter. So we have two tackles who are inferior run blockers and pass block just as poorly(Brick was terrible last season). Slausson is coming off major shoulder surgery and did ok, lets see what's up with him. Moore was hurt last season and hopefully will be better. Mangold is one hit to his knee, he's been very fortunate so far.
There are so many things wrong with the O line, it's going to be a long season.
