For the second time this season, Baltimore Ravens Coach Brian Billick has benched his starting quarterback, today naming Tony Banks as Sunday's starter against the Buffalo Bills in place of Stoney Case.

It "is as simple as having to provide an impetus to make something happen offensively," Billick said.

"It's not an indictment of Stoney Case. . . . Right now I think that Tony and his 43 starts, his experience in the league, is something we need right now to get us off this path that we've taken offensively."

Case has struggled in his four starts, completing just 44 percent of his passes and throwing six interceptions. He has thrown three touchdown passes.

Baltimore (2-4) has scored just one touchdown in its past two games. Against Tennessee, the Ravens kicked three field goals and scored two points on a safety by Ray Lewis before losing, 14-11.

Against Kansas City, they were held scoreless for three quarters until Banks replaced Case in the fourth quarter. He engineered a five-play, 56-yard drive that was capped by a two-yard touchdown run by Errict Rhett. Banks completed 8 of 14 passes for 69 yards as Baltimore lost, 35-8.

Banks began the season as the third-string quarterback behind Scott Mitchell, who started Baltimore's first two games, and Case.

After Case took Mitchell's starting job following a loss to Pittsburgh Sept. 19, Banks was elevated to second string. He has not started a game since Dec. 13, when he was with the St. Louis Rams.

"I've been waiting for a long time, trying to be patient, trying to stay mentally ready," Banks said.

"I'm anxious to help the team get some wins."

Billick did not rule out another quarterback switch should Banks falter.

"I don't know if Tony Banks is the answer or not," Billick said. "It's too much of a dogfight right now.

"We're too close to being on the verge of a team that can compete for me not to try something."

Ravens Note: The Ravens signed free agent wide receiver Marcus Nash today. Nash, who was drafted by the Denver Broncos in 1998, has played in 10 games and caught four passes for 76 yards in his brief career.
