Foles' Stand-Up Act Impresses

The Eagles have been getting it done behind a largely-makeshift offensive line, standing up with a quarterback in Nick Foles that shows grace under fire.

Jason Kelce is expected to miss some time with what's being termed as a hernia. Evan Mathis is still out for another six weeks. Lane Johnson won't be back from suspension for another week.

It's a good thing Jason Peters isn't facing suspension for putting Chris Baker in his place.

Despite all of these gashes poked into the Eagles offensive line, the team is 3-0. Once out of the 49ers game, Johnson returns, and 60% of the intended line will be in place. Best case scenario, the starters are all reunited on November 10. Best case scenario, mind you.

The surrogates haven't been exactly terrible; Nick Foles has gone two consecutive games without being sacked, which is astonishing. Dennis Kelly and Andrew Gardner have played as good as they possibly can, even as the Redskins hyper-aggressive pass rush closed in the walls around their quarterback.

All of the sacks were localized in the first half of the season opener against Jacksonville, five in all, to the tune of 47 yards.

One measurement of a line's potency is a quarterback's Real Passing Yards Per Attempt, a metric employed by Cold Hard Football Facts to weigh the QB's production against the line's margin of error.

The calculation is simple: take the team's passing yards (in this case, Foles is the lone thrower this season), and subtract the yards lost to sacks. In this case, Foles' 978 yards have 47 sack yards removed, bringing it down to 931 net yards.

Next, take Foles' 124 pass attempts, and add five snaps of sacks to it. That's, duh, 129.

From there, you determine the Eagles' Real Passing Yards Per Attempt by dividing 931 by 129.

The result: 7.22 Real Passing Yards Per Attempt.

Thanks to big gainers from Darren Sproles and Jeremy Maclin, of course, the number gets a boost, but that's still behind an offensive line that's been riddled with injuries, readjustments, and a constant struggle against bull-rushers like Chris Clemons and Ryan Kerrigan.

In other words, at this stage of 2014, when Foles drops back to throw, he's averaging 7.22 positive yards per drop back, and he's doing it with a shield of back-ups at his front.

That's more impressive than getting up after the Baker cheap shot.
