In this arms race, Eagles' stockpile may not be enough

We are in the dying days of the NFL's free agency period, and the Eagles' approach, like that of many teams at this stage, is of the Popular Mechanics variety: They are tinkering with the roster's undercarriage, bringing in a Dan Klecko here, a Rocky Boiman there -- serviceable guys who will very likely function well within the larger framework.

Meanwhile, down south, the Dallas Cowboys are employing the People magazine approach. Every other day, it seems, there are breathless reports linking them to Chad Johnson (or Pacman Jones, or Darren McFadden).

So far, it's all talk. But Cowboys owner Jerry Jones told reporters at last month's scouting combine that he wanted to add a ''wow'' factor to his team. And he amplified that in a recent interview with Fort Worth Star-Telegram columnist Randy Galloway: ''I can assure everyone our pursuit of talent is far from over.''
