Cowboys Mailbag:At what point does Martellus Bennett's work ethic, or lack thereof, combine with his

Given the many holes the Cowboys need to fill on the roster, do you think the team needs to trade down in the draft to get extra picks? 

There is an old adage that games are won and lost at the line of scrimmage. If that is true (and I believe it is) then why not invest more resources on the lines verses the skill players? 

The Cowboys have historically done a good enough job in free agency that they could draft the best player available. Obviously, this year is different. Will the team's needs this time outweigh the opportunity to draft the best available player? 

Why the hesitancy from the Cowboys in negotiating new contracts with their star players? Is the team trying to play hardball by waiting to extend them?

With the new kickoff rule, wouldn't it be wise to use a safety or gunner to kick the ball? Hang time is not an issue, so just have him kick line drives? 

Will the new kickoff rules change how the 53-man roster is kept from game to game, knowing some players who were frequently needed on special teams last year may not be as needed this year?

For years, we've heard the talking points of, "The Cowboys don't go after big free agency signings. They're a draft-and-develop team. This is the way they operate." Well, since they haven't seen a Super Bowl in 29 years, is it maybe time for them to change their strategy?

Since Ezekiel Elliott and Tony Pollard were inherited by Mike McCarthy and are now gone, is there a running-back type that McCarthy prefers? Is there one in the draft who is closest to that type?

The question is which position is the most critical for the team to hit on? And does the answer change if you are thinking beyond day one and looking long term?

With no movement on Dak Prescott's extension, if the two sides decide this will be his last year in Dallas, is there any chance this will be an evaluation year to see if Trey Lance could be the man in 2025? 

The 2015 and 2018 classes do not have a single player remaining. There is one player left from each of the 2017 and 2019 classes. None of the first or second round picks from 2015-19 are with the team. Is this draft-and-develop reputation a myth?
