Who does, though? The Ravens have at times, but they have some stinkers as well. The Lions are the new flavor of the week, but the Texans are disrupting them tonight (who themselves have looked both good and bad this season). The Chiefs are winning by a whisker with favorable bounces and calls every single week. They are lucky.
I think the Bills look like one of the top teams in the NFL this year, looking at the entire landscape. They are a legitimate superbowl contender in my eyes. They've been hobbled with injuries and are still finding ways to beat teams by double digits. They've won close games. They've clawed back into games. They've done it with offense some weeks, defense others. The pass and run games have both been formidable. The Ravens game is an outlier, I think.
