At one time, I would have completely agreed with this. However, after seeing Greinke receive a larger contract after opting out, I wouldn't be surprised to see Price do the same if he pitches well this season. Also, if Price is unhappy in Boston, he just might be willing to leave a little money on the table. So maybe he doesn't get quite as much, but he could receive a comparable contract from a team that he would be much happier pitching for.
That said, there are two things working heavily against Price opting out:
1. His elbow
2. The new CBA penalties
