At least Mark Brunell won't have to deal with catcalls from his detractors in Washington, who want the offensively challenged quarterback to be replaced by Patrick Ramsey. Brunell's biggest supporter, Coach Joe Gibbs, believes that the 12th-year veteran is taking too much heat -- from pass rushers. The situation is unlikely to change against the Detroit Lions, who have collected the second-most sacks in the NFL. Despite Detroit's little-known pass rushers, Gibbs views the Lions' front four, especially the right side of the line, as one of the league's best. Gibbs's assertion is backed up by the numbers: defensive tackle Shaun Rogers and right defensive end James Hall have combined for 9.5 sacks. The Redskins have yielded 17 sacks, an average of more than two per game. Brunell has struggled with accuracy on his passes -- he has a career-low and NFL-worst 52.4 completion rate through seven games -- and needs time to make his throws sharper, according to Redskins coaches. Last week, Brunell was sacked four times as the Redskins turned to the pass after falling behind early. Opponents have been countering Washington's pass protection by blitzing heavily, and too often the Redskins haven't been able to cope. Washington has released right tackle Kenyatta Jones and tight end Walter Rasby, who began the season as starters, to bolster pass protection.
