Redskins Mike Shanahan inserted backup Rex Grossman over Donovan McNabb against Dallas because, with the team mathematically eliminated from the playoffs, he wanted to evaluate not only the backup, but the rest of the offensive players with a different quarterback.
Shanahan is curious, too, about what third-stringer John Beck would be able to do. But does that mean Beck will automatically play against either Jacksonville or the Giants?
"As I mentioned before, we play these games to win," Shanahan said. "Rex is going to be our quarterback. Unless something happens, [Beck] won't get an opportunity."
