Joe Gibbs's goal every Sunday is for the offense to produce at least 21 points. But the Redskins rarely accomplish that. Washington has surpassed 21 points just 15 times in 48 games (four of those came during the five-game winning streak to end the 2005 season), with the Redskins 10-5 in those games (11-22 otherwise). .... Over the past three seasons only five teams have topped 21 points less often than the Redskins -- Cleveland (10 times), Oakland (11), Detroit (11), Houston (12) and Tampa Bay (14). Of that group, all but Tampa Bay have been last-place doormats since Gibbs has returned. The average NFL team topped 21 points 21 times in that span.-- Washington Post
