Well of course that'll all be taken into account, but at the end of the day pass rushers are needed to get to the QB.
My point is because the Saints currently own their rights, it'll be cheaper for them to keep them versus shelling out equal money for inferior players or much more money for better players. Under no circumstances are the Saints getting better DEs for equal or less money than they're paying now except when it comes to Foskey. The other option is the draft. The team can't wait until the draft to make decisions about personnel at DE. It's too important.
In an ideal world the Saints would go into free agency and just buy the best DEs available. They can't do that. Talent in the Saints price range just doesn't come available at DE unless it's a Young type situation or a Davenport situation. So trade our underwhelming DEs for different more expensive underwhelming DEs?
