Signing Rasul Douglas did not suddenly make the Washington Commanders the class of the NFC East at cornerback. There is little doubt that the move improved the unit, but what it really did was make their cornerback room more complete. This helps, but it does not erase any other facts that already existed.This article is the first installment of our NFC East Roster Power Rankings series, where every position group in the division will be ranked from first to fourth. The top group receives four points, second place gets three, third gets two, and fourth gets one. The totals will be carried over from post to post throughout the series before giving a final collective divisional roster ranking.Cornerback seems like the best place to start since Washington's situation has changed over the last 24 hours. The Commanders now have more options at the position with Trey Amos, Mike Sainristil, Douglas, Amik Robertson, Ahkello Witherspoon, Darius Rush, Antonio Hamilton Sr., and Tre Hawkins III in the mix.While that is a better place to be than before the signing, it is still not the best cornerback room in the division.4.
