Bills blow out reigning champion Rams in season opener

Josh Allen passed for 297 yards while accounting for four touchdowns, Von Miller had two of Buffalo's seven sacks, and the Bills stamped themselves as a clear contender for the Rams' Super Bowl crown with a 31-10 victory over Los Angeles on Thursday night.

Gabe Davis, Isaiah McKenzie and Stefon Diggs caught TD passes as the two-time defending AFC East champion Bills opened the NFL's 103rd season by overcoming four turnovers and running away with a blowout win in the same stadium where the Rams won the Super Bowl nearly seven months ago.

Allen went 26 for 31 despite two interceptions. He also rushed for 56 yards, scrambling for a 4-yard TD when he stretched the ball over the line with 13:27 to play. The star quarterback took his share of hits, but he also dished them out and showed off a mean stiff-arm while Buffalo's offence under new coordinator Ken Dorsey largely dominated the champs.

"There's a lot to learn, but that second half, that's who we want to be, going out there and executing that way," Allen said. "We were 90% on third down. That's a recipe for success."

Matthew Stafford passed for 240 yards with one TD and three interceptions on a bruising night for the Rams, who lost a season opener and fell below .500 for the first time in coach Sean McVay's six seasons in charge.

"Very humbling night, but one where you look yourself in the mirror and say you have to be better," McVay said. "We weren't ready to go. That's on me. ... There were a lot of decisions I made that didn't put us in the best position to succeed. It was a very humbling night."

The Bills' seven sacks were the most allowed in McVay's tenure with the Rams, who lost two starters from last year's offensive line and attempted to replace them internally.
