Cowboys Mailbag:Why did the Cowboys not release Roy Williams last year, when they could have cut his

With the Cowboys' remaining salary cap money, would you try to sign Lamb or Diggs to extensions, thus helping to secure the team's future? Or would you try to bring in another free agent who could help immediately?

Last week, Dak Prescott said, "The urgency is now." Do you think that kind of self-awareness will really bring some kind of greater commitment from Dak, or will he perhaps feel even more pressure to succeed?

While Jerry Jones said yesterday that he was ready to "go from within," would trading for a left guard to shore up the offensive line ahead of the draft still be a good idea?

Even with the Cowboys bringing Leighton Vander Esch back, am I the only one who thinks they still need linebackers? Do you think we'll see them address the position in free agency or wait until the draft?

I can't remember the last time the Cowboys had such a successful offseason. Where do the collective moves rank in your memory? Do you have to go back to the wheeling-dealing days of the early 1990s?

I have to admit that I was surprised Cooper Rush came back. Were you surprised? What are your thoughts on the Cowboys re-signing him?

Will Brandin Cooks take some pressure off Gallup, allowing him to relax and play? Or is he going to take targets away from him, hampering his comeback, so to speak?

I'm excited with what the Cowboys have done so far this offseason, but I'm still worried about defensive tackle. Should re-signing Johnathan Hankins now be a priority?

With Mike McCarthy now calling plays, how do you see him making the best use of his new talent and the wide receiver group as a whole?

Sports like basketball and baseball have a luxury tax if they go over the salary cap or a certain spending limit. Now that free agency has started, why doesn't the NFL have some kind of system like that?

Dak Prescott seemed to disagree last week when asked if he needed a new voice. Is there any worry that all this change might actually affect Dak negatively?

The Cowboys are back under the salary cap thanks to reworking some contracts, but having some money to play with now, what do you think they'll do in free agency?
