If CC Sabathia opts out, should the Yankees resign him or not?

It is widely expected that CC will out of his contract with the Yankees. It is also expected that if he does, the Yankees are gonna bid with themselves to get him a new deal. Now what if the Yankees don't resign CC Sabathia? By 2012, the Killer Bs will be ready. Brackman should be ready by mid season this year and Banuelos and Betances are projected to appear in 2012. Add those 3 with Phil Hughes and AJ Burnett and that is a 5 man rotation right there. If any of them doesn't pan out, we still have Ivan Nova, Adam Warren, and David Phelps. The Yankees should do what the Angels did this year. Go for depth of rotation rather than an ace followed by 4 others. Who knows, maybe one of the guys can become an ace. Banuelos sure has the stuff. So I think the Yankees should not resign CC. The money is already there for him. If he rejects it, too bad.
