The AFC is just so stacked. I wouldn't be surprised to see any of the Dolphins, Bills, Chiefs, or Ravens represent the AFC, and only mild surprise at the Jets, Chargers, Steelers, or Browns. And at least one of those eight teams won't even make the playoffs. In the NFC, I think it will almost definitely be one of the Eagles, 49ers, or Lions, with the Cowboys and Seahawks behind them.
As for the Ravens, I think they're just too hot-and-cold to win three straight playoff games. 38-6 over the Lions and 37-3 over the Seahawks is great, but losing to the Colts and Steelers and keeping the Cardinals within 7 is not. Which Ravens team will come to play in the wildcard, divisional, or AFCCG? They'll need the former for each one.
