Mike Shanahan isn't going to bite on recent comments by Donovan McNabb that Robert Griffin III won't be a good fit with the Redskins. "I'd like to let the statistics speak for themselves," Shanahan said. "I think I can take the high road." McNabb played for Shanahan in Washington in 2010, when the Redskins went 6-10, the quarterback was benched twice, and there were testy exchanges involving McNabb's agent and the team. "I was misused. Absolutely," McNabb said of his time under Shanahan. McNabb pointed to the records of the quarterbacks Shanahan has employed (Rex Grossman and John Beck with the Redskins, and Brian Griese with the Broncos), besides his own experience in the coach's system, to base his criticism. "You can go by so many different stats," Shanahan said. "The perception, the most basic one people look at is, 'Did you win a Super Bowl at the end of the day?'"
