This feels like one of those NFL years where there are like 4-5 really good teams and the rest of the league is just fodder.
Going by team DVOA, the 49ers, Bills, Lions, Dolphins, Eagles, Chiefs and Ravens have effectively lapped the field on efficiency, with the Seahawks, Saints, Jaguars and Browns the next up, each being below average at one of the 3 facets of football (offense, defense, special teams). I currently have no idea who the bottom half of the playoffs will be in each league, and I don't think it matters thus far.
