Going purely by the weight of each projected starter, the Cowboys look like they could have one of the lightest defensive lines in the league this year. Is that a good or a bad thing?
Life used to be simple in a 3-4 defense. The fat guy was the nose tackle, the two other big guys were the defensive ends.
Today, the Cowboys find themselves in 4-3 defense, and things are getting a lot murkier weight-wise. Because it used to be that in a 4-3 defense you had two big guys who were the defensive tackles charged with plugging the middle, and you had two defensive ends who were a little more athletic than the tackles and were charged with rushing the passer.
