The main question for the NFL's weekend of wild-card games is who will advance, of course. The next big query: Who do you trust?
    Dallas?
    Not exactly a sure thing in the playoffs — at least not since Jimmy Johnson was around.
    Detroit? Even less dependable; the Lions' last postseason win came when Barry Sanders was in the early portion of his Hall of Fame career.
    So when the Cowboys host the Lions on Sunday in the final wild-card affair, it's virtually impossible to predict what will happen.
    "Little different this time of year," says first-year Lions coach Jim Caldwell, who guided the Colts to the February 2010 Super Bowl, a loss to New Orleans. "Obviously, I think every game is tough and difficult I think when you get in the playoffs when it's one and done if you lose. I think it's a heightened sense of intensity."
    Can Detroit handle it? Can Dallas?
    "I think as much as anything else is to take advantage of an opportunity to get better as a football team," coach Jason Garrett says. "Guys embraced the opportunity to play. I think we saw that in the spirit and demeanor we played with."
    They'll need the same approach in the second season.
    Also this weekend, it's Arizona at Carolina and Baltimore at Pittsburgh on Saturday, Cincinnati at Indianapolis on Sunday. Division champions New England, Denver, Seattle and Green Bay have byes.
