You simply don't know that Tyler Smith won't prove to be a good replacement for Tyron Smith, and if I was named Jones, then I would ALSO want to know sooner than later if my recent 1st round pick can handle the job now. So, I don't think the Cowboys are half-assing it. What they ARE doing by talking to Peters is setting up a contingency plan just in case Tyler Smith is not yet ready. Signing a veteran backup before Tyron Smith was injured would just take playing and development time away from their recent draft picks. Signing one about two weeks after Tyron Smith went down, and before game 1 is a good plan.
Listen, the Cowboys gave Josh Ball a very long look at Left Tackle this preseason. That is ultimately a good thing for the Cowboys. Ball fell short, but the reality is he was injured all of last season, and this has really been his first chance to get in the huddle and develop. Personally, I think Ball did some good things this summer - even if he ultimately showed he's not ready. Waletzko also looked like a good pickup in the limited time he got due to being injured a large portion of time in training camp. But he is obviously not ready yet either.
Peters, if he gets signed, becomes the backup plan to Tyler Smith at Left Tackle. Zach Martin is the backup plan at right tackle. Ball and Walesko both get a year of practice to develop and hone their skills against what is looking to be a very stout defensive front being fielded by the Cowboys revamped defense. Hopefully, by mid-way through the year, both Ball and Walesko can make more strides to develop more, and the weekly competition in practice against a good defense will help them get ready for future roles - a future that may come as soon as later this season.
Teams NEED to develop players that are drafted in later rounds. Bringing in a veteran this past summer would have slowed that development. Bringing in a veteran now that Tyron Smith is out is a good plan, but it wouldn't have been a good plan this past summer if the goal is truly to develop your draft picks. Calm down and let things play out. We'll find out on September 11th where Tyler Smith is at in his development. More importantly, we'll find out how quickly he learns from his mistakes on September 18th against the Bengals. Young and inexperienced does not always equate to bad players or bad play.
It makes for a more interesting fan experience to watch how the young guys develop. And it is much more important that the Cowboys be hitting on all cylinders in December and January than in September. By that time, if the Cowboys let the youngsters play, they will no longer be inexperienced, which will accrue to the benefit of the Cowboys - even if they drop a couple of games to 2 of the last 4 Super Bowl teams during September.
