Separating NFL's contenders and pretenders

— -- Nearly half the NFL awoke Monday with winning records as Week 6 neared its end. Ten teams are 4-2 or better, although a couple -- Pittsburgh and Oakland, for sure -- played more like the Cleveland Browns than like teams with real aspirations.

Separating contenders from pretenders is easy at the top, but a dozen teams will wind up earning postseason spots, with probably half of them having legitimate shots at reaching the Super Bowl. Which ones are the real deals? A run through all teams with winning records and a few other notables provides some clarity.

True contenders can trust their defenses. They have quarterbacks who protect the football and can flourish in two-minute situations. They have track records for improving late in the season, and they ideally can win games even when their preferred formula becomes unavailable to them.
