What's the matchup? Detroit Lions (6-2) at Arizona Cardinals (3-5)

When can I see it? 4:15 ET on FOX

What's the tagline? A very hot Detroit Lions team heads to the desert to take on a desperate Arizona team that has hit a 3-game skid and needs a victory to stay alive in the playoff race.

What's the line? Cardinals by 1; Over/Under: 45

What do the experts think? Surprisingly, not everyone believes Mike Martz's offense will successfully breach Arizona's defense enough to win the game. Michael Rosenberg is one of those people:

The Lions are coming off two of their most impressive performances in years – which, of course, guarantees nothing today.

If this game were in Detroit, I’d pick the Lions. But in Arizona, I’ll go with the Cardinals.

Ed McNamara has similar feelings:

Gary the Lions fan has decorated his den with a mural of himself kneeling in front of Matt Millen saying, "Genius, forgive me for ever doubting you." It looks like a classic trap game for Detroit with the Giants and Packers up next. The pick: Cardinals

What do I think? Arizona is desperate for a win -- and they face a Detroit team that has been shaky at points this season. The pick: Arizona, 24-23

Just what is this "Open Thread Idea?" This aptly named "game day open thread" is a forum for fans of the Cardinals (or Lions) to voice opinions and banter before, during, and after the game. I urge you to comment and get a real conversation going, even if it's just a chat with me.
