Here are a few things you may want to know about Week 1 of the NFL season…The 1972 Dolphins were the last team to win the Super Bowl the season after losing the Super Bowl (Miami lost Super Bowl VI to the Cowboys at New Orleans, then defeated the Redskins in Super Bowl VII at the L.A. Coliseum to culminate their perfect 17-0 season). The only other time this occurred was, ironically, the previous season when the Cowboys lost to the Colts in Super Bowl V, then beat the aforementioned Dolphins in Super Bowl VI…<!--more-->The Steelers has won 8 straight season openers dating back to 2003, the longest active streak in the NFL. That success could be challenged this Sunday at Baltimore in a playoff rematch between these AFC North rivals. Meanwhile, the Raiders have lost 8 straight season openers dating back to ’03, also the longest active streak in the league. Ironically, it started the year after Oakland’s last winning season and playoff appearance in ’02, a season that culminated in a loss to the Buccaneers in Super Bowl XXXVII. But something has to give because the Raiders were a perfect 6-0 vs. AFC West rivals last season…The Lions and Rams were 4-0 this preseason, while the Falcons, Chiefs and Raiders did not win a game this summer. While being perfect doesn’t ensure a playoff berth, going winless hasnot been kind to clubs trying to win a championship. Only 1 team has gone winless in preseason and gone on to win a Super Bowl. That would be the 1982 Washington Redskins, who were 0-4 eventually won Super Bowl XVII during the NFL’s strike-shortened (9 games) season…If Kansas City is to repeat as AFC West champions this season, they must continue to minimize mistakes (14 turnovers in 2010, second fewest in NFL) and also continue to evolve ondefense. Last season, under veteran coordinator Romeo Crennel, the Chiefs totaled 39 sacks in 16 games, quite an improvement for a unit that totaled just 32 sacks in its previous 32 games from 2008-09. Todd Haley’s team, which led the league in rushing in 2010, hosts the Bills, which finished last in the NFL in against the run last season…Who knows what could happen if the New York Giants could hang onto the football? Tim Coughlin’s team has had its problems with this issue as of late. The Giants have committed 73 turnovers in their last 32 games (2009-10), after committing just 13 turnovers in 16 games in 2008. So how did Big Blue win 10 games last season despite that many mistakes? Coughlin’s club also led the league with 39 takeaways and became the first team since the ’03 Rams to achieve this odd daily-double…
