If the Washington Redskins have proven anything during their six-game winning streak, it's their own legitimacy.
Washington's down-to-the-wire win resembled previous victories. Griffin delivered another smart, largely mistake-free effort. Rookie running back Alfred Morris pounded the ball for 91 yards on 22 carries. The Redskins' defense -- no juggernaut, mind you -- did just enough to keep Eagles rookie passer Nick Foles from tying the score on the final drive.
Griffin was unhindered by the knee injury that pulled him out of the lineup in Week 15. His accuracy for a rookie is remarkable. RG3 suffered just his fifth interception on the season, but it came off a tipped pass. The rest of Griffin's day -- 16-of-24 passing for 198 yards and two touchdowns -- was another chapter in an outstanding rookie campaign.
A Minnesota Vikings victory over the Houston Texans on Sunday prevented the Redskins (9-6) from sealing an NFC playoff berth, but they have mowed down four consecutive NFC East opponents. If they can take care of their fifth -- the Dallas Cowboys in Week 17 -- the Redskins will win their first division crown since 1999.
