Cowboys Mailbag:Mick's Mail: 07/27

Which player on offense (other than the quarterback) and on defense can the Cowboys least afford to lose to injury, due to either his impact or lack of depth at the position?

Coming off last season, the defensive bar literally could not be any lower. The Cowboys defense could improve significantly and still not be an average NFL unit. Why all the hype?

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?
