The Raiders' 2-0 start was a distant memory Sunday following a 30-23 home loss to the Buffalo Bills.
Unable to capitalize on scoring opportunities or generate any sort of pass rush or defensive consistency, the Raiders saw a competitive slip away in a one-sided second half against a Buffalo team that improved to 4-0.
Buffalo quarterback Josh Allen completed 24 of 34 passes for 288 yards and a pair of touchdowns for Buffalo, which looks like a worthy challenger to New England's run of 11 straight division titles in the AFC East.
As for the AFC West, the Raiders (2-2) looked light years from being able to compete with the Kansas City Chiefs, who happen to be next week's opponent at Arrowhead Stadium.
Allen threw touchdown passes of 26 yards to Gabriel Davis and 11 yards to Cole Beasley. He also scored on a 1-yard sneak. Running back Devin Singletary tacked on a 2-yard touchdown run and Tyler Bass converted a 34-yard field goal.
For the Raiders, Derek Carr had a 3-yard touchdown pass to Jason Witten, a cosmetic 7-yard pass to Nelson Agholor with 1:29 left and Daniel Carlson had field goals of 54, 39 and 25 yards. The second touchdown pass made Carr the all-time franchise leader in touchdown passes with 151, passing Ken Stabler. The last drive covered 80 yards in eight plays, but all that was left was for Buffalo to recover the onside kick to end the game.
Carr completed 32 of 44 passes for 311 yards as the Raiders had 383 yards of offense.
