The day after: “They’re upset …”

JACKSONVILLE – Doug Pederson remains confident. Very confident.

A day after a turnover-plagued loss to the unbeaten and NFC East-leading Philadelphia Eagles, Pederson on Monday said he believes the right lessons will be learned. The Jaguars’ head coach also said this:
