Mailbag: Why all the hype for defense?

Any concern there is no coach on the staff with prior head coaching experience? In the past, there have been a few coaches or coordinators who were head coaches. Who does Brian Schottenheimer turn to if he needs some in-game advice or suggestions?

Outside of quarterback, what position group on this current team is the most valuable? And which one do you think needs to have a really good year to get the Cowboys back in the playoffs?

Now that Christian Parker is a defensive coordinator and not a position coach, how much interaction will he have with the individual players? In particular, how much influence will he have on the development of players in the secondary?

Dallas has some cap space to make a solid free-agent addition if needed, and there are some big names still available. Which position do you think the Cowboys can help themselves the most with an addition? And do you think it will happen?

The NFL season is now 17 games, and the NFL actually slates a bye in Week 14? With three weeks to go? What's the point? Everyone is already beat to dirt. Why aren't byes set for all teams in the middle of the season? How does a bye SO late in the schedule help any team?

Based on the culture head coach Brian Schottenheimer is continuing to build, do you see any impact of Malachi Lawrence holding out on signing his rookie contract?

Since it's a contract year for both DeMarvion Overshown and Dee Winters, should Dallas extend one of them before the season starts, where it would cost the team less now? If they wait until the season is over, it may cost more if they have outstanding years. And wouldn't potentially losing both in free agency because they became too expensive put them in the same linebacking predicament next year?

I think it's safe to say Dallas is one of the best teams at finding diamonds in the rough with undrafted players. Having said that, it seems to me that undrafted players have panned out more often for the Cowboys than actual seventh-round picks. Do you guys believe that is a fair assessment? And if so, why is that?

What does the coaching staff and front office see in Marist Liufau that make them think he will be successful rushing the passer?

Again, Dallas has three games in 11 days, and then there's the brutal travel. I understand the attraction to air Cowboys games in prime time, but at some point, is the onus on the NFL to protect its players? Secondly, is the team able to sign off and approve the schedule, reaping some of the blame?

The Cowboys signed a pretty good wide receiver, Marquez Valdes-Scantling, just after the draft, but no one seems to be including him in the battle for the third receiver spot. He has a lot of experience in the league and has had some good seasons. What do you think?
