Re Davis: I already said my two cents and see there is not one poster to respond with a realistic alternative...
The Cardinals should be and likely, I think, will be working on Hayes extension this season.
Dansby's situation is a little more tenuous, all depending upon the causes and resolution of his "injury/holdout" drama that occured earlier this year. Only someone with true inside information could know the status here. It appears on the outside that it has been resolved but
Regarding Macklin: I would like the Cardinals to keep him here. But the starting corners are now and, in lieu of unforseen circumstance such as injury, etc., for the forseeable future will be Antrell Rolle and Eric Greene. (I am beginning to think Greene may be the better corner of the two, but I like them both.) So Macklin would be kept as a #3 at best; chances are he will be playing elsewhere next year.
All the others are non-critical and will be dependent upon the individuals expectations as compared to the teams. If they and the team are in agreement as to worth and value (not the same thing) then re-sign them. If not, so long...
What about Darling vs. Huff? If it came to only one of the two which one would you re-up?? I think might go with Darling, but I would need a strong young backup in the wings...
