2013 NFL offensive line rankings

It's been tough sledding so far for Eli Manning and the Giants' porous offensive line. Jeremy Brevard/USA TODAY Sports

The Giants' offensive line has played its part in Big Blue's offensive tailspin.

New York ranks 26th in yards before contact and 30th in short-yardage rushing during its inauspicious 0-4 start. Only the Lions have had a higher percentage of rushes for no gain or worse than the Giants this season.

As for pass protection? Ten sacks in the past two games are no aberration. Injuries to starters David Diehl, David Baas and Chris Snee may have set up the Giants' offensive line to fail, but it's certainly obliged.

The Giants check in at 30th in the debut of our NFL Offensive Line Rankings. With help from Stats & Info's Hank Gargiulo, we've taken a look at how each team rates this season in six statistical categories:

• Yards before contact per rush
• Short-yardage conversion percentage
• Sack percentage of total dropbacks
• QB pressure percentage with a blocking advantage (more blockers than rushers)
• Line stability
• Penalty yardage

Here's an in-depth look at some of the top units and several that need major help.
