Cowboys 1-3 start not all Romo's fault

For all of the blame that will be leveled on QB Tony Romo after the team's loss to Tennessee on Sunday, the Dallas Cowboys defense has looked horrible in home losses to the Chicago Bears and Tennessee Titans.

Wade Phillips' unit didn't get many takeaways last season, and this season they haven't stopped many clubs through the air. This season, Dallas is in the bottom half of the league in sacks after finishing in the top seven in each of the last three seasons. And only two teams have fewer interceptions than the Cowboys' two.

When a quarterback has a 400-yard passing game, it looks great on the resume and lousy on the ledger. There have been seven such performances this season and those quarterbacks are 1-6. The lone win came when Matt Schaub and the Houston Texans beat the Washington Redskins in OT, defeating 400-yard passer Donovan McNabb in the process.

The Buffalo Bills’ new-look defense continues to be a liability, giving up 200 yards or more on the ground for the third straight week, and at least 30 points for the fourth straight game. The Bills defense allowed each of those numbers just four times all of last season.

When it comes to the defending Super Bowl Champion New Orleans Saints, turnaround may be fair play for one of last season's most opportunistic teams. On Sunday, the Arizona Cardinals totaled three return touchdowns (offensive fumble recovery, defensive fumble recovery, interception) in their win over New Orleans. Last season, the Saints allowed three return touchdowns in 16 games.

By the way, the Cardinals have looked awful on the road and are down to an undrafted rookie free agent quarterback. But sometimes we forget the Cardinals have not had a losing season under head coach Ken Whisenhunt, dating to 2007.

Cleveland Browns' QB Jake Delhomme remains a turnover machine. Starting with his implosion for the Carolina Panthers in the 2008 NFC Divisional Playoffs, Delhomme has committed 31 turnovers (27 interceptions, four fumbles lost) in his last 14 games.

While the Kansas City Chiefs certainly have their offensive limitations, their defensive unit, under coordinator Romeo Crennel, has made major strides. Kansas City has yet to give up 20 points in four games so far this season. Last season its defense allowed at least 20 points in four of their first five games (all losses).

Denver Broncos' QB Kyle Orton continues to pile up the passing yards, but what does it really mean? Let’s not forget that the Saints QB Drew Brees threw for 5,069 yards in 2008, but finished 8-8 and out of the playoffs. Denver is tied for last place, two games behind the AFC West leader.

Dating back to last season, QB Josh Freeman and the Tampa Bay Buccaneers are 5-2 in their last seven games. The Bucs opened the 2009 season 1-12 and used three different quarterbacks along the way (Byron Leftwich, Josh Johnson and Freeman) before the latter took over for good.
