SportsDay's Jon Machota answered questions in a chat Friday. Here are some highlights.

Question: Dez Bryant hasn't been a full participant in OTAs; how does he look to you? What's he saying?

Jon Machota: He looks healthy, motivated and energetic. I'm not a doctor and I haven't seen any X-rays, so I don't know exactly how close he is to 100 percent but he certainly appears headed in the right direction. He doesn't appear to be limited by the ankle/foot. We've seen him in pre-practice walk-throughs the last two weeks and he's running routes and catching passes from Romo and Moore. Dez will be ready to go when he's needed, but the Cowboys will be very cautious along the way.

Question: You've been at OTAs, what are some things we Cowboys fans should feel good about and not so good about?

Jon Machota: They should feel good about where Tony Romo and Dez Bryant are regarding their health. This team must have those two on the field throughout the season if they are going to make a run. They should feel good about an offensive line that still hasn't reached its ceiling. They should feel good about the offense in general. When everyone is healthy, they're completely loaded with weapons. What they should be concerned about is this defense, especially the pass rush. I wonder where the pressure is going to come from. There are a lot of questions to be answered up front. Losing Collins obviously doesn't help. On the back end, who is going to force turnovers? I think there are just a ton of questions on defense for even the biggest of fan to say they feel comfortable with this group. For this defense to be competitive, Lee, Scandrick, Rolando, Byron, Mo, Crawford, Lawrence and Gregory all have to stay healthy and make an impact all year.
