OXNARD, Calif. – One preseason game is in the books and four remain, but there are plenty of things to wonder about.

So on it is to our third training camp installment of Five Wonders:

** On the grand schemes of things Tony Romo not playing a series against Miami is not that big of a deal. With issues on the offensive line and Romo’s lack of offseason work because of the back surgery, the team thought it was wiser to sit the quarterback against the Dolphins. Well, I wonder what they were thinking about in 2010 and ’11 when they didn’t sit Romo with offensive line issues when he had to play more. In 2010 at San Diego, Robert Brewster had to play right tackle with Marc Colombo and Alex Barron hurt, but Romo played four series. In 2011, the Cowboys made the decision to part ways with center Andre Gurode before they played at Minnesota and had undrafted rookie Kevin Kowalski start with Phil Costa out. It was the first time Romo took a snap from Kowalski all summer. And Kowalski was the third rookie to start that night with Bill Nagy and Tyron Smith. There was no worry that night either. Again, it’s not a huge deal that Romo didn’t play against Miami, but it’s just notable given what happened in recent history.

** Now that Larry Allen has been inducted into the Pro Football Hall of Fame, Charles Haley figures to be the next Cowboy to make it. Haley has been a finalist the last few years and the feeling among voters is that the question is “when” not “if” Haley will make it. But I wonder who will be the next Cowboy to take up a lifetime residence in Canton, Ohio. Perhaps Chuck Howley, Lee Roy Jordan, Cliff Harris and Drew Pearson get a look from the Veterans Committee. But what of the more-recent era Cowboys? Darren Woodson should gain consideration but the safety position has never been a popular pick among the voters. Woodson was covering slot receivers before it was fashionable for safeties to do so. He was truly ahead of his time in some ways. I’m not sure there is another 90s Era player that will get a look, but Jerry Jones will be in there one day. Maybe soon too.

** Forever, it seems, the Cowboys have found success stories in undrafted free agents: Romo, Miles Austin, Stephen Bowen and Dan Bailey are among the more recent vintage. But I wonder if there will be one undrafted free agent to make the team this year. Really. The leader would appear to be linebacker Brandon Magee, who could become a big part of the special teams’ units. Even those who haven’t seen Eric Rogers play a snap seem to think he can be Keyshawn Johnson, but the Cal Lutheran product has a lot of work to do in earning a spot. Safety Jeff Heath has been an under-the-radar guy and Jakar Hamilton, who received $10,000 to sign, has yet to make a mark in camp. There is a lot of time to make a push but right now there isn’t a lock yet.

** It’s hard to gauge just how interested the Cowboys are in Brian Waters. They know he is available, but they haven’t really put the full-court press on him just yet. Maybe they wanted to see Ronald Leary in a game before going ahead with it. But if they are going to sign Waters, I wonder if it’s too late. He did not take part in an offseason program last year and did not sign with a team. He was not with a team this offseason either. What kind of shape is he in? If the Cowboys bring Waters in, it’s not for a workout. It’s to sign him. He signed with New England in 2011 a week before the season started and ended up in the Pro Bowl. But in players’ years, that could be a lifetime ago.

** Let’s close with a game involving a 53-man roster projection. I wonder if the final spot or two comes down to a seventh linebacker, fourth running back, a 10th offensive linemen, a sixth wide receiver or a ninth defensive lineman? If that’s the case, then Magee, Phillip Tanner, Darrion Weems, Anthony Armstrong, Tim Benford, Eric Rogers or a George Selvie are fighting for one or two spots right now. Right now, I’m not sure the ninth or 10th offensive lineman is on the roster. Armstrong has had a really good camp and his speed separates him from some others. Selvie could be insurance for Anthony Spencer being banged up and helped himself with Sunday’s two-sack effort. Tanner also helped his cause. Based on what Tanner, Selvie and Armstrong did against Miami, it looks like the Cowboys will have a decision to make as opposed to trying to find players to keep.
