The thing is this team could run the ball earlier this season, with a similarly suspect offensive line.  What's changed is that defenses (starting with the Giants) are loading up the box now, stopping the run, and daring Siemian to pass.  Yes, he makes completions if he has time - most every NFL QB does.  But he eventually throws picks.  Or fumbles when he gets sacked.  He doesn't make plays with his feet and he seems to be continually surprised when he gets sacked when he holds the ball.  The play calling doesn't help - not enough screens or boots; neither does the TE blocking or lack thereof.  But unless you have Tom Brady or Peyton Manning accuracy and football IQ, you need to be able to make plays when they aren't there as an NFL QB.  How many of those has Siemian made?  I can't think of one.  But I can think of plenty of times he's fumbled when he wasn't protecting the ball or thrown to the wrong team.  In addition to his latest INT and fumble today, he had two sure INTs dropped.
