Last week

Quarterback Trent Edwards made his first start of his NFL career and led the Bills over the Jets, 17-14, for the Buffalo's first win of the season.
At stake
The Cowboys have started a season 4-0 for the first time since 1995 when the team won Super Bowl XXX. And it's never too early to start thinking about homefield advantage as the Green Bay Packers are also undefeated. ... The Bills are far behind the Patriots in the race for the AFC East, but the most important thing right now is the development of rookies Edwards and running back Marshawn Lynch.
Key matchup
Cowboys receivers Terrell Owens and Patrick Crayton vs. Bills corners Jabari Green and Terrence McGee. Owens has caught 15 touchdowns in his past 16 games, while Crayton set career highs with seven receptions for 184 yards and a pair of touchdowns. Look for the Cowboys, under first-year offensive coordinator Jason Garrett, to go to the air against Greer and McGee, who each had an interceptions last week against the Jets.
