Jones alluded to two losses -- at Seattle in Week 2 and to Chicago at Cowboys Stadium in Week 4, when Dallas' defense was almost completely healthy -- as part of the reasons why he let Ryan go.
The Cowboys lost to the Seahawks, 27-7, but two special-teams turnovers put Dallas into a 10-0 hole in the first quarter. As a defense, the Cowboys were missing only one starter, nose tackle Jay Ratliff, to injury.
In the 34-18 loss to the Bears, quarterback Tony Romo threw five interceptions, with two of those returned for touchdowns. The Cowboys were missing two defensive starters to injury in that game, Anthony Spencer and Ratliff.
