Donovan McNabb's agent has criticized the Redskins and coach Mike Shanahan for his plan to bench McNabb in favor of backup Rex Grossman against the Cowboys. "Disrespectful is probably not strong enough of a word," Fletcher N. Smith, McNabb's representative, said. "Donovan has handled himself with nothing but class, not just in Washington but as an ambassador for the league. To treat him this way ... it's beyond disrespectful."
