Philadelphia Eagles left tackle Jason Peters put the biggest smile on the faces of fans on Sunday, when he walked over to the crowd and began signing autographs for the many Eagles fans in attendance at StubHub Center.

The biggest smile probably came from a marine, who got an autograph from the big guy, when he got his prosthetic leg signed.

That same marine explained to Jeff Skversky of 6abc that he lost his leg in Afghanistan and that Peters signing it was the greatest moment of his life.
