OK, your qualification of which teams are good and which are not is kind of whack. Except for the undefeated teams at the time, pretty much most of the decent teams were at .500 or worse. Cincinatti, who is on FIRE right now, was 1-3. So Philly at 2-2 still qualified as a good team which the Cowboys beat. The Cowboys also beat "one of the best teams in the NFC" yesterday. When the 49ers won all those Super Bowls in the 80s, they never played a good team except for their AFC games or the playoffs. The Rams were sorry, the Falcons were sorry and the Saints were sorry all through most of the 80s. Are you going to sit there and say the 49ers, based on their season record, weren't any good?
Your Pats got skunked 31-0 by Buffalo, whom the Cowboys beat. The Rams were 2-2 when we beat Philly, too. Are the Rams a bad team at 8-3? Your logic about which tema are good and bad holds no argument. If the Cowboys were (and I know it's a long shot) go on to win the Super Bowl, you would find some other thing to nitpick: "they didn't win by 35 points!"
