Then the problem is evaluating players, not in "undervaluing" the position. And if just signing the biggest name or the guy who's been to the most Pro Bowls on the free agent market has proved to be an utter failure from 96-08, it makes no sense to revisit that approach. The Cowboys brought in a different OL guru and are in the process of trying to implement a new scheme/philosophy to better utilize under valued players. People are so quick to call this current approach a failure because there hasn't been a payoff in 2 years (never mind the fact that it took about 3-4 years for the OL of the 90s to come to fruition), but they're advocating going back to an organizational offensive line philosophy that was a complete and abject failure for the better part of 10+ years.
