Valid. I would love to see them heading into the playoffs red hot but two things to consider. The Cowboys know they didn't need that game. They are locked into the 5th seed and it would take a miracle for them to win the division or improve their seeding. The second thing to remember is they are dealing with a boatload of injuries. I think LVE and Pollard both would have played if the Cowboys needed the game. At the same time, I think they want to try to avoid further injuries to their starters.
I just think the mental part of the game is harder than the physical part, especially when there is nothing to play for. If Dallas wanted that game badly, I have no doubt they would have played better and blown out the Titans.
Having said that, some of the same things we saw the last two weeks continue to plague them, like the pass coverage for instance. The injuries to Brown and Lewis have really set this defense back in a big way.
