How meaningful are first impressions?
A lot of opinions were formed on the basis of Kickoff Weekend in the National Football League. Week Two's games may help determine if those judgments were valid.
Are Atlanta, San Francisco, Baltimore, Dallas, Washington and the New York Jets as good as they looked the first week? Are the Buffalo Bills, Miami Dolphins, Cincinnati Bengals and Kansas City Chiefs as bad as they looked?
One thing is certain, There will be at least four unbeaten teams and four winless teams after Week Two is over because four of the games match 0-1 teams and four match 1-0 teams.
Something to consider: Last year, Week One winners went 7-9 in Week Two. Of the season's 12 playoff teams, only eight won their openers.
A look at the schedule:

Game of the Day

Ravens (1-0) at Eagles (1-0)
Kickoff: 1 p.m.
The line: Eagles (-2˝).
The scoop: Ravens, along with 49ers and Falcons, were probably the most impressive teams on Kickoff Weekend. Baltimore handled respectable Bengals team routinely. Bad news for Ravens' opponents: 30-plus defensive stars Ray Lewis and Ed Reed aren't over the hill yet. ... Eagles sneaked by punchless Browns, 17-16, despite rolling up 450 yards.
Outlook: New-look Ravens can match points with Michael Vick and the Eagles, even in Philadelphia. Baltimore, 27-20.

Top attractions

Lions (1-0) at 49ers (1-0)
TV: Ch. 2, 8:20 p.m.
The line: 49ers (-7).
The scoop: Niners held Packers to 324 yards at Lambeau which may not sound impressive but ... Also, SF had no turnovers, repeating last year's trend when Niners led league with only 10. Meanwhile, Matthew Stafford of Lions threw three picks in close win at home over Rams.
Outlook: Niners were 8-2 at Candlestick Park last season, with both losses in overtime. San Francisco, 21-13.

Broncos (1-0) at Falcons (1-0)
TV: ESPN, Monday, 8:30 p.m.
The line: Falcons (-3).
The scoop: This will be only the third time Peyton Manning has played in Atlanta as a pro. He's 1-1 there, with the loss coming in his rookie year (1998). Manning threw for two TDs in win over Pittsburgh. Most of his completions were in 15-20-yard range. ... Matt Ryan led Falcons to scores on eight of nine possesions.
Outlook: Julio Jones becoming huge weapon for Atlanta. Denver DBs get tested. Falcons, 31-27.
Jets (1-0) at Steelers (0-1)
TV: Ch. 4, 4:25 p.m.
The line: Steelers (-5˝).
The scoop: Steelers have won their last nine home openers, but Jets have won three of the last four times the teams have met. ... Pittsburgh controlled ball 35:05 but still lost at Denver on Sunday night.
Outlook: Unfortunately, Jets may be for real. New York, 27-20.

Best of the rest

Chiefs (0-1) at Bills (0-1)
TV: Ch. 4, 1 p.m.
The line: Bills (-3).
The scoop: The Kansas City defense was about as ineffective as the Bills' last week, but the Chiefs were missing four starters. Pass rushing LB Tamba Hali is due back from his suspension, but the other three are questionable. ... K.C. gave up scores on Atlanta's first eight series last week and had four turnovers. Still, the Chiefs were in it until missed field goal (for possible tie) in the third quarter.
Outlook: K.C. receiving corps of Bowe, Breaston, McCluster and TEs Kevin Boss and Tony Moeaki are huge threat to leaky Bills pass defense. Chiefs, 31-27.

Saints (0-1) at Panthers (0-1)
Kickoff: 1 p.m.
The line: Saints (-2˝).
The scoop: Losing to RG3 and the Redskins at home was a huge setback for the Saints, even considering the turmoil surrounding the team. ... Carolina managed only 10 yards rushing in 14 attempts in loss at Tampa Bay.
Outlook: Saints have won five of last six against NFC South rivals and should be real angry. New Orleans, 31-17.

Browns (0-1) at Bengals (0-1)
Kickoff: 1 p.m.
The line: Bengals (-7).
The scoop: Cleveland is last in the league in several offensive categories after rookie QB Brandon Weeden's ineffective performance in loss to Eagles. Is that Colt McCoy warming up in the bullpen? Cincy was handled at Baltimore, but has won last four against Brownies. ... Marvin Lewis (69) has more wins than any coach in Bengals history including the great PB (Paul Brown), Forrest Gregg and always colorful Sam Wyche.
Outlook: Bengals can't lose home opener to punchless Browns. Cincinnati, 20-10.

Texans (1-0) at Jaguars (0-1)
Kickoff: 1 p.m.
The line: Texans (-7).
The scoop: Houston has won last three over Jaguars and is coming off impressive win over Dolphins. With short time to prepare, holdout Maurice Jones-Drew ran for 77 yards and caught three passes for 18 more in OT loss at Minnesota.
Outlook: Blaine Gabbert had career game at QB last week and Jags still lost. Texans are better than Vikes. Houston, 31-20.

Kickoff: 1 p.m.
The line: Patriots (-13˝)
The scoop: Kevin Kolb, hero of last week's win over Seattle, starts at QB for Cardinals in place of injured John Skelton. ... Pats' Bill Belichick can pass Chuck Knox (193) on all-time coaches' win list, which tells you that Ground Chuck wasn't so bad.
Outlook: Pats won, 47-7, last time teams met in 2008. It won't be quite as bad this time, however. New England, 37-14.

Buccaneers (1-0) at Giants (0-1)
Kickoff: 1 p.m.
The line: Giants (-7)
The scoop: Big Blue fans nervous, but under Tom Coughlin Giants have been late-season bloomers. ... Jersey native Greg Schiano comes home as coach of Bucs. ... Tampa Bay coming off home win over Carolina when it showed a very conservative offense - 36 runs and 24 passes.

Redskins (1-0) at Rams (0-1)
Kickoff: 4:05 p.m.
The line: Redskins (-3˝).
The scoop: Rams looked much improved in first game under Jeff Fisher but still lost at Detroit. Redskins and rookie QB Robert Griffin III opened some eyes by going into New Orleans and winning. ... Two of the NFL's best coaches - Fisher and Mike Shanahan - match wits.
Outlook: Hard to figure this one? Rams will have a book on RG3 to work with. Fisher and Rams keep it close. Washington, 17-16.

Cowboys (1-0) at Seahawks (0-1)
TV: Ch. 29, 4:05 p.m.
The line: Cowboys (-3).
The scoop: Dallas has 12 days to prepare for Seahawks after their win over Super Bowl Giants. ... Seahawks lost opener at Arizona, losing late lead. ... QB Tony Romo of 'Boys had strong opener against Giants.
Outlook: Romo has led Dallas to three victories in a row over Seahawks, but all were at home. Dallas, 28-16.

Raiders (0-1) at Dolphins (0-1)

The line: Raiders (-2˝).
The scoop: Both teams are short of receivers. Injury to Oakland long snapper led to three busted punt attempts which led to three San Diego field goals in Raiders' 22-14 loss. ... Miami rookie QB Ryan Tannehill had horrid opener (39.0 passer rating) in loss at Houston. Wait til he hears it from fickle Miami crowd, biggest front-runners in NFL.
Outlook: Dolphins have won 12 of last 15 against Silver and Black. Raiders, 1-6 at Miami since win in 1990, are due, 20-13.

Titans (0-1) at Chargers (1-0)
Kickoff: 4:25 p.m.
The line: Chargers (-6˝)
The scoop: New starting QB Jake Locker passed for 229 yards and a touchdown in loss to New England last week. Problem was ground game produced only 20 yards (1.3 average) and Chris Johnson had just 4 yards in 11 attempts. ... Chargers QB Philip Rivers completed 24 passes, but for less than 10 yards a completion, in victory against Raiders last Monday night.
Outlook: Chargers have won last seven against Titans/Oilers, with five coming in San Diego. San Diego, 30-20.

Dog of the day

Vikings (1-0) at Colts (0-1)
Kickoff: 1 p.m.
The line: Vikings (-3)
The scoop: Adrian Peterson already is the leading rusher (6,818 yards) in Vikings' history. He passed ESPN's Robert Smith last week. ... No. 1 pick Andrew Luck had a decent debut for Colts in loss at Chicago, but three INTS led to 52.9 rating.
Outlook: Eventually Luck will be dynamite indoors at the Luke, but not yet. Vikings, 27-17.
Last season's record: 10-5 outright; 7-8 versus spread.
