Bob Sturm had some quotes in his column on the Athletic that were mostly positive from an Oakland beat writer:
Cooper, the opposite of a diva, has been a little more vocal this season than he has in the past, telling Gruden and Carr after plays that he was open.
And like Mack, he is a perfect citizen off the field and a hard-worker who his teammates all respect. You hear the national pundits now chiming in with “Cooper is not passionate about football,” but that is absurd. He has spent far more time watching game film on his couch at home than he ever has in a nightclub.
Now, one can definitely say that Cooper is not passionate in general, or is too nice and doesn’t show much emotion at all on the field. But no one complained about that when he caught 11 passes for 210 yards against the Chiefs last season.
