@Cowboys_Chile:I liked how tight end Martin Rucker played Thursday. What are his chances of sticking around and what role could he have?
Nick:I still think he's a long shot. Let's not judge the fourth quarter of a preseason game because he's going to look pretty good as a receiving tight end. Can he block in the trenches and play special teams? Those two questions must be answered in his favor for him to have a shot.
Josh: I wouldn't reserve a spot for him just yet, because I think he's still clearly the fourth best tight end. If you went that heavy at the position, you probably don't keep a fullback, and I think Jason Garrett wants a true fullback. So while he may be improved, I don't give him a great chance to make the team.
@GodsSon1206 :What's the most significant change Jason Garrett made in training camp and preseason practice, and what effect will it have on the team?
Nick:The most significant change has been putting them in pads every day at 2:30. That's the change and he only hopes it will make them a more physical team.
Josh: Being in pads almost every day is the biggest tangible thing, but I think he has a totally different attitude and demeanor about him than Wade Phillips did, and his energy can rub off on the players. 
Mailbag: Is Jason Witten the next Dan Campbell?
If Witten surrounds himself with an experienced staff, do you feel he'd be the right guy for the job like Dan Campbell was able to do in Detroit?Â
