Sometimes looks are deceiving. A lot of NFL teams are not as good as they looked a few weeks ago and others are not as bad as the cynics think.
Based on what we saw the first four weeks of the season, we were ready to proclaim the Atlanta Falcons, New England Patriots, Oakland Raiders, Green Bay Packers and Los Angeles Rams as solid playoff contenders. The Kansas Chiefs looked like the dominant team in the AFC.
On the other hand, the New Orleans Saints and Miami Dolphins looked like losers. Would the Chicago Bears, San Diego Chargers and San Francisco 49ers win more than one or two games, and what's wrong with the Pittsburgh Steelers?
Sunday, the Dolphins and Bears were among seven underdogs who triumphed. Pittsburgh knocked Kansas City from the unbeaten ranks at Arrowhead while the Jets threw a scare into the Patriots, the 49ers lost by only two at Washington and the Chargers won on the road at Oakland.
It's time to reassess a lot of conventional wisdom.
A capsule look at Sunday's Week Six NFL games:
Game of the day
Dolphins 20, Falcons 17
The scoop: Miami rallied from a 17-0 deficit to take the lead on two Jay Cutler touchdown passes and two Cody Parkey field goals. DeShon Jones intercepted Matt Ryan's pass with 39 seconds to play when it appeared Ryan was driving the Falcons toward a tying field goal or winning touchdown after they had reached the Miami 26.
Why the Dolphins won: Atlanta was shut out in the second half and moved the ball on only two of its four series after the half.
Not as good as ...

However, Tom Brady had the Pats even by halftime and they took the lead for good on his second TD pass to Rob Gronkowski, a 33-yard play, in the third quarter.
Why the Patriots won: They got a huge help from the Referee Tony Corrente and the officials on the field and the video replay center in Manhattan.

After he went out, the Vikings took a 14-10 lead as Jerick McKinnon scored on a 27-yard pass from Case Keenum and ran 3 yards for another score. The only scoring in the second half was on three Kai Forbath field goals for the Vikings.
