Kate Hairopoulos, Cowboys beat writer for SportsDayDFW.com and The Dallas Morning News, answered questions about the team in a live chat Tuesday. Here are some highlights.

At this point who do you think is Dallas' best CB?

Kate Hairopoulos: This may not have an obvious answer. Think about it - there's a lot of buzz about the rookies, particularly Chidobe Awuzie and Jourdan Lewis, but they've only been through a minicamp. Lewis still has to deal with a trial for his misdemeanor domestic violence charge on July 24 in Michigan, as training camp begins. As with many things we'll discuss here in mid-July, we'll know more when training camp starts in a couple of weeks. Nolan Carroll's availability is in question after a DUI arrest. Anthony Brown showed a lot as rookie, but can still grow. So would you believe Orlando Scandrick? Does that make you nervous? When the 30-year-old is healthy he can still get the job done. Will he be able to remain healthy for the entire season?

Which defender lost -- Wilcox, Carr, Claiborne, Church -- do you think Dallas is going to miss the most?

Kate Hairopoulos: Barry Church was a co-captain on defense and ranked second to only Sean Lee in tackles. The others had pluses and minuses, but they certainly had experience, which the secondary will be lacking this season. Of course, the Cowboys believe they had to get younger and faster and not stick with the same ol' lineup they've been putting out there.

Who do you think is a good candidate to lead Dallas in INTs this season?

Kate Hairopoulos: Jeff Heath does have a knack for executing when he has the chance to get a takeaway, and he's proven that in only limited action at safety in previous seasons. Now he's expected to get a chance to start, and will at the least see the field more. Last year Barry Church had two interceptions and seven other Cowboys had one a piece. Heath picked off Aaron Rodgers in the playoff game against Green Bay.

What are the Cowboys going to do if the Chaz Green experiment fails?

Kate Hairopoulos: The left guard position will be closely watched at training camp. With La'el Collins moving out to right tackle, will Green be able to make the switch to guard AND stay healthy? The health issue has been his biggest problem, as he proved reliable at tackle last season when Tyron Smith was out a couple of early games. Or will the Cowboys want to keep him as a swing tackle and go with the likes of veteran Jonathan Cooper or Joe Looney or Byron Bell even at left guard?
