I think I know what you mean.
Not quite the same, but I get a little concerned over meaningless stuff, as if it's bad mojo. For example, that weird stat about Stafford being something like 0-17 on the road versus winning teams bugs me. I mean, something has to give at some point, right? There's another stat about Romo being 1-3 in the playoffs, and if he gets to 1-4, apparently it will be the worst winning % by any QB in the post season in NFL history. We'll all be hearing that one repeatedly this off season if this game doesn't go the Cowboys way.
Then there's more tangible things that worry me, like no Melton, and possibly no Hitchens and no Free. Calvin Johnson on Brandon Carr doesn't make me feel great. A rookie O-lineman being named an All-Pro, and now running into about as touch of a test as he'll likely have his rookie season seems to have me more concerned than most.
I suppose I also feel like there's just this assumption that Dallas simply has to much for these Lions to handle. I suppose I look at these teams and they seem as if they might match-up pretty well. It could very well come down to the team that takes better care of the football, but to others, it seems to be a foregone conclusion that Dallas wins this game.
Besides all that, I think I just don't want the season to end with a thud. Say what you will, but expectations change. While 12-4 may have been a gift when one thinks about expectations in the preseason, losing a Wild Card game would still feel like a kick to the junk. Besides, I think we're all tired of hearing "there they go! It's the same old Cowboys! Told ya' so!" If they come out and lose this game, we'll hear at least another year. I mean, some of these guys don't even analyze the Cowboys anymore, they just jump right to repeating the same old stuff. Until Dallas proves them wrong, that's how it's going to be, so I really hope this is where Dallas proves them wrong.
