[Prefatory Note: What follows is not my insight. I learned it in a convo with my good friend, and a good friend of PTI, Booger McFarland. It tells me why others who have played or studied the sport know more than I do and why no one is hiring me as GM of any NFL football team]
To say the least, the Dallas Cowboy defense has been porous this season is to state the obvious truth. Much of the criticism has been aimed at their D-line, so when they traded this week they came under substantial criticism for trading for a cornerback Joey Porter, Jr. instead of for a D-lineman. Here's what Booger explained. If the defensive secondary is leaving receivers open, no D-line, no matter how good, is going to stop the opponent. If the defensive secondary is keeping receivers covered, no quarterback can succeed no matter how good his O-line. Given that Porter is one of the best cornerbacks in the league, if not the best, this was the right move for Dallas.
