CLEVELAND, NOV. 4 -- The Buffalo Bills ran up the most lopsided win in their history Sunday, beating the Cleveland Browns, 42-0, and extending their winning streak to six games. They may have also ended Bud Carson's tenure as coach of the Browns.

Thurman Thomas scored three touchdowns as Buffalo (7-1) kept pace with Miami atop the AFC East. In doing so, the Bills gave Cleveland its worst shutout loss in the team's history, eclipsing a 34-0 trouncing at Kansas City earlier this season. It was the worst home loss ever for the Browns, who lost two road games by 48-point margins in the 1960s.

The Browns, who have a bye next Sunday, are 2-7 and off to their worst start since being 1-8 in 1984. If a coaching change is to be made, this could be the time since Cleveland has a bye next week and it would give a successor two weeks to prepare.

Carson, weary of all the speculation that he is about to be fired by owner Art Modell, appeared ready to abdicate.

"I better go home and think about it myself, to be honest with you," Carson said. "The last thing I want to do is be part of a football team that can't win. If I'm that part, I'll know it and I'll step away from it. Right now, I think it looks worse than it is."

If this was Carson's last game, he went out with a flourish, starting Mike Pagel at quarterback over Bernie Kosar. It was the first time since 1985 that Kosar missed a start when he was healthy.

Buffalo's defense, however, didn't care who was back there. Bills linebacker Darryl Talley had two interceptions, returning the second one 60 yards for the Bills' final touchdown.
