Some people think that the 1st week is a little outrageous, scores sometimes get out of hand, and isn't a real true indicator of a teams' season, as some teams just aren't ready for the season. I think just the opposite, and although there are exceptions, it many times says a lot about what your season will be like. A loss in the 1st game of the season is quite disheartening and not a good sign. I think the 1st game says much about where a teams' talent is at, and then from game 4 on, coaches that are good at film study have more effect.
Here are the scores from game 1 2012, and a little analysis:
Jags 23 Vikes 26 - Vikes probably should have won by a wider margin
Cowboys 27 Giants 24 - Cowboys made the playoffs, Giants didn't, losing at home was not a good sign for the G men
Patriots 34 Titans 13 - Patriots made the playoffs, Titans were a sad team, losing big at home a bad sign
Redskins 40 Saints 32 - Redskins made the playoffs, Saints didn't, not a good sign to lose at home in the opener
Bills 28 Jets 48 - 2 bad teams, home team wins. They both finished with the same record, probably should have been a closer game
Seahawks 16 Cards 20 - This game was an anomaly. Seahawks lost on the road, probably should have won as they made the playoffs, Cards didn't
Steelers 19 Broncos 31 - Steelers didn't make the playoffs, the Broncos did
Dolphins 10 Texans 30 - Right on, Texans made the playoffs, Dolphins didn't
Eagles 17 Browns 16 - 2 bad teams,
Panthers 10 Bucs 16 - 2 teams that didn't make the playoffs, the home team won
Bengals 13 Ravens 44 - Bengals did make the playoffs, game probably should have been closer, but then again the Ravens went on to win it all, so it's about right
Rams 23 Lions 27 - Neither team made the playoffs, although the Rams were close. The home team won in a close game.
Falcons 40 Chiefs 24 - Chiefs in for a bad season losing at home, Falcons made the playoffs, had home field in the playoffs, good start winning big on the road.
Colts 21 Bears 41 - Should have been a closer game, Bears were 10-6, near playoff team playing at home. Either it should be been a closer, or Colts should have won a game considering their final records were just 1 game apart, it was almost right the Bears won, it should have been a closer game.
49ers 30 Packers 22 - Both playoff teams, SF finished a half game higher, and went much farther in the playoffs than GB
Chargers 22 Raiders 14 - bad teams, the Chargers finished 3 games ahead of the Raiders so score was about right.
So of all the scores, a few maybe should have been closer, but they were almost all spot on with how the teams' seasons went, with the exception of one game, that was the Seahawks losing on the road to the Cards.
IOW, the Vikes losing at the Lions was NOT a good sign for this season.
