Cowboys Mailbag:What are going to be the best or most intriguing position battles this offseason?

Why do you think Joe Looney hasn't signed with anybody yet? 

I personally think cornerback is the position easiest to miss on. Is Patrick Surtain II a sure thing?

With Aldon Smith headed to Seattle, can't the argument be made that edge rusher as just as big of a need as any position on defense?

Do you think Surtain would still be there at 15 or do you feel Dallas has decided to go with the best available player?

If the Cowboys trade down, how low do they go before they must consider trading out of the first round completely?

With 10 draft picks, do you see the team trading up for more quality starter type players? 

Where do you see Leighton Vander Esch playing this season? 

Just for fun while waiting for the draft: Do you think there's a scenario where the Cowboys trade their second-round pick to move back into the late first round to get someone?

Do you think if Ja'Marr Chase falls to No. 10 that the Cowboys would draft him? 

If the NFL passes this latest rule change regarding numbers, could and should Jaylon Smith move into Tony Romo's No. 9 jersey? 

Patrick Surtain and Penei Sewell are both on the board and they get an offer to move back into the 20s but pick up a first-round pick next year. Do you take the deal or pick a player? 

We've heard a lot about the Cowboys' additions on defense, but what are your thoughts on Ty Nsekhe at offensive tackle?
