Cowboys has to worry about its defense

The Cowboys should not be too confident in its solid starters at almost every position. There are solid starters, but not enough.

In wide receiver positions, Roy Williams and Patrick Crayton are the only two elite wrs in the group. All others are in lack of experience or have health problems. The same situation to safety positions. Ken Hamiln was a pro-bowler two years ago, and Sensabaugh is the only one in the group who can match Hamiln's level. Except for the two, others are in lack of training.

The problem is there is really limited time. There is not enough time for a lot of training, and overworking will probably cause more health problems.

So as I say in the title, the Cowboys has to worry about its defense.
