The shots kept on coming, one after another, and Carson Wentz absorbed them all with a smile. Four fans at the last practice of training camp had spotted the bright red jersey, and they swarmed to it with smartphones in hand. One after another, Wentz obliged them, stooping down to selfie height and mugging for the camera, smiling head-to-head as if each were an actual friend. A franchise quarterback will always have his critics, but one thing beyond dispute is Wentz’s embrace of the role.
