You know it only takes one or two plays to turn the game around. Like for instance, on one of Pollard's goal line runs in this last game, the interior blocking was very good, Pollard had a seam that he could have easily gotten in to make a td, but one of the defenders was totally unblocked, and tackled Pollard well before he got back to the LOS. If the Cowboys had simply chipped that defender, very likely Pollard scores a td instead of the Cowboys having to settle for a fg on that drive, and the entire complexion of the game might have changed.
But it seems that's always the case with Dallas in the last few years. Either it's an offsides penalty when the defense has stopped the other team stopped and would have to punt, or a dropped pass, or a missed tackle, or a non-call on a penalty against the other team, or our receiver falls down and an int ensues or any of a myriad of other misfortunes, dumb play calls or such.
Sometimes it seems this team is snakebit....
