Strongest schedule? Only the Patriots and Jaguars will play (likely) above-.500 opponents 8 times. This is really remarkable with the Pats, since this type of metric always underestimates the quality of the opponents of good teams and overestimates the quality of opponents of bad teams. Given that the Pats have faced 3 of the top 4 other teams, it's hard to argue that any team had a tougher season than the Pats.
Weakest schedule? Only the Seahawks will slide through their season facing good teams just 3 times (Miami, by comparison will play 7 above-.500 teams).
Flimsiest record? The Giants have 9 wins against weak opponents and 4 losses against strong opponents. The Bills also haven't beaten a good team - and will need to beat at least one of the two more they face to get into the playoffs.
