The Buffalo Bills were too strong for the reigning Super Bowl champions in the NFL's season kickoff on Thursday night, shutting the Los Angeles Rams down in the second half to run away 31-10 winners on the road.

It was a stylish start for the Bills as they received the opening kick and marched down the field in nine plays, culminating in a 26-yard touchdown pass from Josh Allen to Gabriel Davis for the first score of the season.

That set the table for what looked like it may be a shootout, but the rust was still clearly not shaken off as the next five combined possessions resulted in three turnovers and two punts.

A beautiful throw from Matthew Stafford found Cooper Kupp in the back corner of the endzone late in the second quarter, and after Allen's second interception of the game, a 57-yard field goal as time expired from Matt Gay had things tied at 10-10 going into halftime.

There were warning signs for the Rams as they needed three Bills turnovers to remain competitive, and when the visitors cleaned things up in the second half, the hosts had no answer.

The first three Bills drives of the second half all resulted in touchdowns, with Allen rushing for one score, finding Isaiah McKenzie for a short-range touchdown, and heaving long for a 53-yarder to Stefon Diggs to complete the rout.

Stafford could only find success throwing to star receiver Cooper Kupp, who finished with 13 catches for 128 yards and a touchdown from his 15 targets, while the five other players to catch a pass combined for 16 catches for 112 yards on 25 targets. He also had three interceptions after one more in garbage time.

Allen finished 26-of-31 for 297 yards with three touchdowns and two picks, adding 10 rushes for 56 yards and a score on the ground. Diggs was his top receiver with eight catches for 122 yards and a touchdown from nine targets.
