Seattle Seahawks WR D.K. Metcalf has impressed QB Russell Wilson with his football knowledge so far as a rookie.’Everybody knows about his ability to run and everything else, and jump and catch and all that. You guys have been talking about that for months, but I think more than anything else, it’s his brain and how he processes information and how quickly he understands it. He’s really intelligent. He really understands the game really well. He takes coaching really well. He gets extra work. He’s a legit pro wide receiver. He’s everything that everybody was talking about in terms of what he’s capable of and more.’
