As a regular person who is not a professional athlete, the amount of money Correa is likely to make is imaginary to me anyway. If I were him, I'd tell myself I was set for life no matter what happens, and just sign with a team I knew I'd enjoy playing with for ten years.
On the other hand, a ten-year contract is very long. Even if Correa does love Buxton, Falvey, Rocco et all as much as he says he does, if he gets the contract he wants, he has a good chance of outlasting all of them. Who knows if he'll like the next front office, the next manager, his future teammates, etc? From this perspective, he's better off getting all the money he can (or at least picking someplace where he likes the climate), because liking the team is a crapshoot over such a long period.
And then on the other hand, for someone who has millions of dollars in their bank account, there really is a difference between getting $325 million and whatever lowball offer the Twins are likely to make.
