You just can't make a judgment yet. Last year worked for A's and we needed that bat among another tons of things. Bailey was a complete bust last year. We have to wait. Hopefully Bailey is not made of glass/under perform this year... Again.
As I said, Theo had a great time in Boston, but the last, say, 4 years of his tenure were horrible, reason why he is no longer here. He left the team in red numbers in the BL (considering only baseball operations) according to Forbes.
