Rookie report: David Amerson - Washington Redskins Blog - ESPN
I think patience is necessary with any rookie. Let’s wait and see how the kid does where he is having had a season under his belt and (hopefully) more reliable play around him.
Re Matthews vs Benjamin, I think JM is a better starter as of now but KB might have greater upside. I’d personally keep an eye on Donte Moncrief out of Ole Miss. He had something of a down year but there’s a lot to like about his game. I’ve read a few detailed reports on him suggesting he high points the ball as well as anyone in this class, and is a savvy route runner with enough speed to be a deep threat.
