That's the thing, people who watch baseball dont generally account for defensive matrix. they comment on that later in the article. They further suggest if you take his defensive matrix and cut them in half, you will get a player in cameron who is worth about as much as Bay.
it makes sense that less fly balls/line drives accounting for hits will help the team win. Bay is pretty horrible defensively. the logic seems there...
I guess we'll see, I am not saying I necessarily agree with everything in the article, but we know the Sox are very interested in advanced statistics...
Regardless of the plebian minds of those who watch baseball, what about those people who evaluate baseball for a living? There are some pretty savvy GMs out there besides just Theo. What about Cameron's agent? If Cameron truly was as good -- or better -- than Bay, why is he getting $7 million per season, while Bay will be getting $16 million+? Shouldn't one of the other GMs said "hey, wait, we can get a $16 million player at $7 million; why aren't we all over this?"
I'm sure Cameron's agent couldn't demand Bay-like money with a straight face, and Cameron was smart enough not to ask for it.
First, it wasnt a comment about 'plebian' minds. when I watch a baseball game, I am not sitting there watching an of fail to get to a ball saying, oh man, another guy may have gotten there, whereas I can see a player hit a home run. the point was that offense in baseball seems to resonate and produce tangible results, whereas defense (not including obviuos errors) could easily go either unnoticed, or not given much weight.
Second, as the article notes, Cameron is 36 (will be 37) while Bay is 31.
Third, not all baseball evaluators believe in the advanced metrics.
I guess we will see, it's all a moot point if in game one of the season, Bay breaks his leg. or Cameron does. we'll have to wait and see what the statistics come out as. there is at least an argument that the team as a whole could perform better based on the increase in defense then what it would do with a breaking down Jason Bay (part of the reason that the offer at midseason with bay fell apart, based on the sox fears about bay's shoulder)
