ORCHARD PARK, N.Y. -- Not often does a quarterback have such an inefficient performance yet walk off the field a winner.

Cleveland Browns quarterback Derek Anderson completed two passes on Sunday afternoon and defeated the Buffalo Bills 6-3 in Ralph Wilson Stadium.

Anderson's 11.8 completion percentage is the second-worst since the NFL-AFL merger for a winning quarterback with at least 15 pass attempts.

The Browns have been involved in the three most uneconomical-but-triumphant passing performances.

In 1970, Browns quarterback Don Gault was 1 of 16 (6.3 percent) in a victory over the Pittsburgh Steelers.

In 1974, Steelers quarterback Terry Hanratty was 2 of 15 (13.3 percent) against the Browns.

Bills legend Jim Kelly has the fourth-lowest completion percentage in a win. He went 4 of 21 (19 percent) to beat the Carolina Panthers in 1995.
