When Brian Cashman took the plunge and signed CC Sabathia during the 2008-2009 offseason, it was the start of the Yankees' new commitment to building a solid starting rotation. The main factor that kept them out of the World Series after 2003 was their lack of top notch-quality starting pitching and their lack of rotation depth. Sabathia has given them more than what they hoped for and then some since signing, but one thing that's always lagged behind is the quality of depth behind him in the rotation. Former top prospects like Phil Hughes and Joba Chamberlain didn't pan out, nor did CC's fellow big FA signing from that offseason. The lack of back end depth became such an issue that Andy Pettitte had to be brought back and then brought back out of retirement to fortify the rotation.
He's not around this year, nor are Hughes and Chamberlain, but for the first time in a while it appears as though the Yankees have finally solved that depth problem for the short and long-term futures. There are still a few things that need to be ironed out, but the lay of the rotation land this year is much brighter than it's been in a while.
