I am not sure that having a game under its belt is really that much of a positive for Dallas. This is the second consecutive travel week for a team that is playing primarily backups. THe starters for the Cowboys aren't expected to play much at all.
THeir HC never tries to win in the preseason.
The travel, in addition to training camp, is going to add up for players who are not used to heavy workloads. Arizona’s stars should see a little more playing time as well. Head coach Kliff Kingsbury did confirm that star quarterback Kyler Murray will get some snaps on Friday night. Murray will likely only play one or two series, though, so the bulk of the reps will be split between Colt McCoy and Chris Streveler. Wide receivers DeAndre Hopkins and A.J. Green will probably make brief appearances as well.. McCoy is a better backup than Gilbert or DiNucci, who are likely going to be disrupted by Arizona’s aggressive defense.

Take the Arizona Cardinals late on Friday night.
