Cowboys Mailbag:Do you agree with the mock drafts that the Cowboys would pick Nebraska's Prince Amuk

With the Cowboys deciding to get deals done with both Brevyn Spann-Ford and Ryan Flournoy in the same night, is there a reason they both happened like this, just before the season?

We know the Cowboys needed to improve their defense during the offseason. However, does the offense need to improve in any way this year? Pass or run blocking? Third-down efficiency? Improvement in the red zone? Getting off to a good start in the first half or second half?

With the addition of Christian Parker and so many new pieces, how many games do you think it will take to really know what we have on defense?

One of my favorite plays is the screen pass. Tony Dorsett, Emmitt Smith, Marion Barber and Ezekiel Elliott used to do very well and gain good yards with it. Why is it not used that much now? Is it due to personnel? The screen pass seems to have been replaced by the jet sweep.

When Brian Schottenheimer began coaching last year, he said he wanted the Cowboys to have the best culture in the league. It seems like this year that new culture is now on full display, and everyone is on the same page. What do you think? How many more games can culture alone win you?

Camden Brown obviously got everyone excited with his outstanding training camp, and he deserved to make the team. But how much do you think we'll actually see him contribute this year? After all, there's a lot of talent ahead of him in that wide receiver room and even on special teams.

How do you see Christian Parker using all the safeties the Cowboys have invested in? Particularly Jalen Thompson, P.J. Locke, Malik Hooker and Caleb Downs. Will we ever see them on the field at the same time?

Were you as surprised as I was to see the team release Joe Milton after the progress he's made since last season? Do you agree with the thinking there?

What are your thoughts on Broderick Jones being acquired to not just be the swing tackle, but to actually compete for the starting right tackle job? Is he really a threat to Terence Steele?

Any surprises for you with the final cuts, whether it was a guy making the team or being left off?

I'm assuming by now the final roster has pretty much been determined. But who do you think really needs to show something in this last preseason game to get one of those final spots?

I have concerns about DeMarvion Overshown at middle linebacker. Love the guy, but he seems built to play the Will or Edge. So do you think rookie Jaishawn Barham has done enough to start at middle linebacker? He seems like a big hitter who is a better fit for the position.
