How you feeling? Redskins-Vikings

As the Washington Redskins get set to face the Minnesota Vikings at 4:25 p.m. ET at FedEx Field, here's one reason for Redskins fans to feel good and one reason for concern.

Feeling good: It appears as though rookie quarterback Robert Griffin III will start at quarterback after leaving last week's game with a concussion. The Redskins' offense clearly depends on Griffin, and his presence will allow Washington to run a variety of looks and plays the Vikings haven't seen yet. The Redskins' best chance to win the game against the 4-1 Vikings is to catch them off guard, and their chances of doing so improve greatly with Griffin available to play.

Cause for concern: There are a few, but the main one on offense is that Minnesota has the ability to make the Redskins one-dimensional. The Vikings are allowing only 78 rush yards per game and 3.2 per carry, and that could make life difficult for rookie running back Alfred Morris. If the Vikings are able to limit Morris, that could put too much pressure on Griffin to win the game by himself. And it appears as though, even if top wide receiver Pierre Garcon is able to play, he'll at least be limited by the stubborn foot injury he suffered in Week 1.
