Correia's decision to stay or opt out is going to be on someone's shoulder, not his. If he stays, he'll look like a great guy, solely looking to build a championship for Twins fans. If he opts out, it will probably, make him look like a great family man, doing what's best for his family in the long run. The Twins will never will a bidding war for correia's services for a long period of time.
So, he can just sit back, do his thing, and collect his dough. About the only thing he has to worry about, is getting hurt.
