A couple guys on the line are better than last year (LT, RG), but that RT position is still a swinging gate, as is LG.  Although I agree Siemian has issues at QB and doesn't guarantee great offensive performance if the o-line is great, last game was a nightmare for the line.  It needs help too, simply because the run game depends on it as well.  

The last two games the RB's combined for 4 yards/carry against the Chargers and 2.5 yards per carry against the Giants (I'm excluding Siemian's runs because they're not designed runs).  Those numbers stink, especially since they're not when they're really needed.

First, they need to get rid of the 7-step drop.  Then, get Garcia help, cause he couldn't push a bicycle downhill.  Let the defenders on the edges get steered to the outside and behind Siemian, so there's a pocket to step into.  Also, give the RT help when he's got a Bosa in front of him.  I hardly saw any chipping on either edge.  They do it all the time against Von and it works.
