CC has a ring and a Cy Young, plus four other top five CYA finishes. He also has six All-Star appearances and more than 3,000 strikeouts. For the sabermetric kids, he cleared the 60 bWAR threshold and his career ERA+ of 116 is certainly high enough to qualify. On top of all that, he was a pleasant personality and played his final 11 seasons as a Yankee.
I think he's in first ballot next year, along with Ichiro and Billy Wagner.
