Bills...31 Rams...14

ST. LOUIS -- For the first time in 16 years, the Buffalo Bills are 4-0. Unlike the previous two weeks, there was no need for late-game heroics.

Jabari Greer’s 33-yard interception return was the go-ahead score in an 18-point fourth-quarter salvo that finished off the go-for-broke St. Louis Rams, 31-14.

After three blowout losses and amid rumors he might be fired during the team’s bye week, Rams Coach Scott Linehan benched quarterback Marc Bulger in favor of 38-year-old Trent Green. Linehan had six new starters in all, four on defense. The shakeup worked for a while, with rookie receiver Donnie Avery scoring on a 37-yard pitch and the defense sacking Trent Edwards four times in the first half.

The Bills’ first defensive score of the year -- also Greer’s first career touchdown -- came off an overthrown pass.

St. Louis (0-4) lost for the 17th time in 20 games.
