The hottest free agent to sign in Philadelphia not named Darren Sproles or Malcolm Jenkins came in the form of the man responsible for the most famous play in NFL history. Or at least the worst single play in New York Jets’ history. Mark Sanchez was brought in to back up Nick Foles, and has shined in training camp. But does Sanchez have the trust of his team?

Though he has been reportedly great at training camp and in the preseason, Sanchez’s early success means nothing in terms of his long-term standing with the team. Looking back on his days with that other team from New York, Sanchez started 62 games but accrued just 33 wins. In those contests the former USC Trojan completed 55.1 percent of his passes for 12,092 yards and 68 scores. However, he did throw 69 interceptions. How can a turnover machine with only 1,028 completions garner trust with the Eagles?

Sanchez has one thing going for him, that being playoff experience. In both 2009 and 2010 Sanchez brought his team back for the win in the fourth quarter, and has four total playoff wins with just two losses. It is this experience, and less so his ability as a quarterback, that makes him so valuable to the Eagles.

On top of his playoff experience is that fact that Philadelphia has no other bona-fide backup on the team. Matt Barkley, another former Trojan, has never shown that he would be a capable replacement should Foles falter. The same could be said for G.J. Kinne, who has more experience on an Arena football team than in the professional spectrum. Regardless of Sanchez’s statistics, the Eagles must learn to trust in him due to the fact that they have no other choice if the worst were to happen with Nick Foles.
