Are the Eagles a better team with Mark Sanchez at quarterback?

While the answer to that question is up for debate, one cannot argue against the results.

The Eagles have posted a 3-1 record since Sanchez took over for an injured Foles, and the team is averaging six more points per game in Sanchez's starts.

A key factor during the Eagles' recent stretch of success has been the limiting of turnovers. The team still leads the league in turnovers, but while they averaged 2.6 turnovers per game in Foles' starts, that number has dipped to 1.8 with Sanchez under center. Less turnovers obviously equate to more scoring opportunities, and finishing off drives is something that Sanchez has also done more efficiently than Foles.

The Birds are scoring on nearly half of their total drives with Sanchez under center (2.4 points per drive), while they only scored on one third of their drives under Foles (1.7 points per drive). Before Foles' injury, the Eagles were only scoring touchdowns on 35% of their red zone trips; the lowest rate in the NFL. Since Sanchez took over that number has jumped up to 55%.

ESPN hypothesizes that Sanchez's success may be the result of a quicker release. From ESPN:

Sanchez’s passes have been thrown an average of 2.45 seconds after the snap this season, quicker than Foles’ 2.73-second average. The difference might seem minimal, but of the 39 quarterbacks with 100 passes this season, Sanchez’s time from snap to release ranks as the 11th-quickest. Foles’ ranks 33rd.”

Less looks downfield may also play a part in Sanchez's statistical superiority over Foles. Again from ESPN:

One of Foles’ biggest faults this season was his deep passing. Foles threw the ball at least 30 yards past the line of scrimmage 22 times this season. He hasn’t played since Week 9, and that’s still within three of the league lead. Foles completed four of those passes (18.2 percent), and although three of those were touchdowns, he also had four interceptions deep. Sanchez has done a better job of picking his spots, going 3-of-6 on passes thrown at least 30 yards downfield with no interceptions.”

Sanchez has been far from perfect, but his ability to take care of the ball and push it in for points at the end of drives has served the Eagles well and has allowed them to perform at an even higher level than they were earlier in the season.
