Chiefs back in business as star QBs go down - five things from NFL week two

Super Bowl champions Seattle look the real deal again after beating the Arizona Cardinals 31-7 for a 12th straight win.

Drew Lock showed he is no ordinary back-up quarterback with three touchdown passes to Jaxon Smith-Njigba, including an 82 yarder that is the longest of the talented receiver's career.

The Seahawks lost Walker to the Chiefs but have retained a remarkable 17 of 22 starters and 44 of their 53-man roster from last season's title win.

That consistency should see them go close again, but they'll face a rejuvenated San Francisco 49ers in their division, who are also 2-0 after beating the Miami Dolphins 35-15.

Showing no signs of jet leg from their victory over the Los Angeles Rams in Australia, the Niners scored touchdowns on their first five possessions to blow Miami away - Christian McCaffrey scored twice, George Kittle also found the end zone and Brock Purdy accounted for three scores.

With the 49ers having their defensive stars back from injury Kyle Shanahan's squad look the total package once again.

The Cincinnati Bengals also look more well rounded this season after winning a 20-6 battle in Houston, thanks to an early touchdown of the season contender catch from Ja'Marr Chase.

We expect fireworks from Chase and Joe Burrow, but having a defence capable of keeping CJ Stroud out of the end zone, and sacking him four times in a road game is the biggest reason for optimism among Bengals fans.

The Philadelphia Eagles were on the ropes against the Tennessee Titans until Jalen Hurts threw the winning touchdown pass to Darius Cooper with just nine seconds left in the game.

Although not as impressive overall as other 2-0 sides, that ability to win games at the death is a familiar trait with Philly - and will make them dangerous all season again.
