Dino isn't downplaying CDRW because he thinks he can dupe the Pitt coaching staff into thinking he is a bad player. Dino is downplaying CDRW because he is a true freshman playing in his first game, and only played one half of football. He is also downplaying CDRW to squelch any question as to who the starting QB is on this team. He is playing it exactly right.
BTW, Dino is allowed to say all those things and still start CDRW against Pitt. No harm at all
And Shrader started this game because Dino most likely thought that a semi-healthy Shrader was better than a healthy freshman backup. He can be excused for being wrong in this instance. As Dino has said before, if you pull out your starting QB (when talking about Dungey), you better be really right.
