"He competed in the first half ... hopefully he can build on that," Gruden said.
Gruden added that he doesn't expect McCoy to dress Saturday.
Griffin displayed more comfort running the offense than any time this season and flashed a bit of his formerly famed mobility -- including a would-be touchdown run that was overturned before halftime.
Gruden added that he will try to build the offense around Griffin's strengths.
"He's got every chance this week against the Philadelphia Eagles to take this position and run with it," the coach said.
A tumultuous season is coming to a close for the Redskins, but perhaps if Griffin stands out in the two final tussles the quarterback can add a silver lining heading into what could be another whirlwind offseason.
