WASHINGTON (AP) -- Kirk Cousins looks like a good backup plan to quarterback Robert Griffin III for Washington.
And running back Roy Helu looks like a good No. 2 to Alfred Morris.
Those were two of the initial impressions from the Redskins' first preseason game. With Griffin and Morris getting the night off, Cousins and Helu had strong performances in Thursday night's 22-21 win over the Tennessee Titans.
The Redskins started three rookies in the defensive backfield.
Safety Bacarri Rambo learned a lesson in open-field tackling when he was embarrassed by Chris Johnson on a 58-yard touchdown run.
Safety Phillip Thomas left the game with a sprained left foot.
Cornerback David Amerson had the best game of the three and nearly had an interception in the first quarter.
