Why the Yankees should forget CC. What? They signed him? Awesome?

I was all set to wake up this morning and write my "Why I'm over CC Sabathia" post detailing the many reasons why the Yankees should stop waiting around for him to decide if he really wants to play in New York, cut bait with their massive contract offer and instead worry about bringing back Andy Pettitte and signing Derek Lowe to solidify the pitching rotation, and signing Manny Ramirez to protect A-Rod (we're really still pondering whether this would be a good idea?) before CC half-heartedly decides to give New York a shot and ultimately flames out under the glare of the media, his record-setting contract and the endless availability of restaurants offering 24-hour delivery.
Instead, I woke up to learn that not only did the Yankees and CC take the first steps in this direction, but the club sweetened the pot with another year and $20 million. Am I excited that the Yankees now have a legitimate ace? Hell yes, of course. I love CC as a competitor and, by all accounts I've seen, one of the all-around good guys in baseball. It just worries me that a guy who was so on the fence and trepedatious about playing in the Bronx for this long is all of a sudden going to carry the 2009 Yankees back to the World Series. For that kind of money and for his stature, Sabathia can't be stepping to the podium and putting on the pinstripes thiking, "Maybe this will work out ok." This decision needs to come with a world-beating, "Let's make this happen," attitude. CC is known to put immense pressure on himself, which will only compound any potential doubt in the face of the massive external pressures he is about to face. That all being said, I still don't think that he will be a flop (and I don't buy into the concerns of many about his physique after so many years of ardently supporting David Wells, the elderstatesman of big fat lefties). Far from it. He's one of the best pitchers in the league and will be good for the Yankees both on the field and in the clubhouse, where he's known as a great teammate who brings people together (something I believe the Yankees have sorely lacked in the A-Rod era). It's a move the Yankees had to make, and maybe in the end it really did simply come down to money for Sabathia. Fine. The problem lies in the way the process played out and the doubts raised along the way. As a Yankees fan, I'm pretty sure I should be overcome with delerious excitement this morning. Instead, I'm just cautiously optimistic. My only hope is that CC doesn't feel the same way.
