Cowboys Mailbag:Mick's Mail: 07/27

I am wondering why the Cowboys decided to sign Von Miller instead of Bobby Wagner? Not that I'm unhappy. I am just curious as to the decision-making process between the two.

What goals should the Cowboys players and coaches have for the first preseason game against the Seahawks? What do they need to accomplish? What do the coaches need to learn about the players?

I know every year fans ask if the starters are going to play during the preseason, and the typical answer is no. But with a whole new defense (players, scheme and coaches), do you see the Cowboys letting them stretch their legs for a series or two? Do you wish they would?

The last two years when the Cowboys scrimmaged the Rams, things didn't seem to go well for the good guys. What were your overall impressions this time around? Could you see any difference?

Which scrimmage do you think will be the most telling of our defense, the Rams or Saints? What do you think those practices will show us about the progress they're making?

Dak Prescott is heading into his 11th season as the starter, and he has produced exactly two wild-card wins. Should he be taking some heat?

How does the coaching staff navigate players who are training camp heroes but during preseason games they don't deliver? I can't imagine having to decipher if a player is just a practice stud or someone who can actually translate that level of play to the field.

Would you wager future picks and the future of the players currently on the team to bring in a new player? If the Cowboys go out and make a big trade, then one or two players probably don't see the playing time they possibly need to fine-tune their skills. Is a move like that worth it?

Who are the undrafted free agent signings you are excited to see at training camp?

With a limit of 16 padded practices in training camp, do you think that's enough for teams to be able to confidently assemble a roster?

New defensive coordinator Christian Parker is trying to bring violence and attitude to this team. So who's "that dude"? Who is the guy who, if you had to walk into a rough bar at 2 a.m., you are picking on this current defense to make sure you get out in one piece?
