FRISCO, Texas (AP) ��� Jeff Heath agrees the Dallas defense hasn't had the impact it did early last season, when that unit often covered for a sagging offense and kept the Cowboys from falling too far out of the playoff picture.
The seventh-year safety also doesn't want to overstate how he and his defensive mates were playing a year ago.
"The idea that we were this perfect defense last year is just not true," Heath said. "I think it's something that you're always trying to get better. The results of these last three games haven't been what wanted them to be. But I think we have the right approach."
