The vets played below their capabilities, they had injuries that they couldn't overcome, and they were way too slow in bringing in many of the young players. Everyone legitimately complained about them under performing last year, so I don't really think last year's record is a very good barometer for next year's predictions. They should be better, even without Correa.
I'm beyond disappointed they didn't improve the team with a big time free agent or two as it was easily within their means, but they should be better next year anyway, simply by letting the younger, more talented players get more at bats and innings. As much as I hate this team getting away with a low payroll, I don't want them clogging up the roster with mediocre vets just because they have money to spend.
