The NFL has officially hit December as playoff races are heating up around the league. In what was one of the wildest weeks in recent memory, 12 games were decided by seven-or-fewer points -- tied for the most in a single week in NFL history.

We saw likely playoff teams in the Chiefs (two points), Texans (three) and Vikings (one point) win narrowly as favorites again. Do you consider tight wins against shaky (or worse) opponents a cause for concern, or something to be encouraged by going into the postseason?

It's never easy when teams have to part ways with their best players. I imagine it's even harder when they have to do it mid-season. Come to think about it, I can't think of many times that's even been necessary.
