The "status quo" worked for the Giants twice in the last 5 seasons, for the Packers last year, the Steelers, and Colts.
This is how teams operate. They have regional scouts who report to the team talent evaluators (numerous titles, not just GM), who report these to coaches and executives. Teams then compile the info and create the Draft Boards, and Free Agency plans.
I am sorry that we are not unique, but not since the days when the Cowboys were using computers (and no one else was) have teams been that different in their personnel policies. That is really just the truth.
Dallas is unique in really only one aspect. Jerry is a celebrity owner who likes the spotlight. I have learned not to care about that. In all other ways we are pretty similar to the rest of the NFL.
