Ozuna would be sweet. But the premise was finding the underrated free agents, which is what I suspect will be at least part of the plan. Why sign Ozuna when Springer is right there, too? And is just a little bit older, a lot better, local, has connections with the team (former college teammate of Matt Barnes) and grew up as a Red Sox fan?
Last year was Ozuna's one year "prove it" deal where he tried to bounce back offensively and destroy a ruined defensive reputation. Unlikely he settles for another one year deal, and no idea what type of years he wants. Pederson is actually a good (not great) defensive outfielder if not in CF. Ozuna was a better outfielder using defensive metrics early in his career, but he had some issues in St. Louis in his last year there. And then there is also the legitimate concern with Ozuna is whether or not he gets a Qualifying Offer. Right now, the theory is Bloom won't be signing anyone with one. It doesn't matter whether or not any of us think it should be a factor. There is the very real possibility that it is with the only person whose opinion counts.
Of course, the most likely LF in Boston next year is still Benintendi. While Boston will need to add an OF, the obvious need is a CF. Ozuna has played there, but not regularly since 2016 and not at all since 2017. While Pederson has played CF more recently, he is not very good at it.
Springer, on the other hand, is the best CF of the bunch, and by a lot. Of course, despite his being a perfect fit for multiple reasons mentioned above, I think neither he nor Ozuna are not going to happen...
