This is his last chance for a big score, most likely.
What's a big score in his case? What is the maximum in years and money that he can realistically hope for? 5 years @14M/year? Even that seems out of reach, but let's say that's what he's looking for. Which teams are likely to give that to him. If you intersect the teams that need a firstbaseman, and don't already have one with a large contract, and who might be inclined to make such a deal the list dwindles fast. In fact, I see only Texas and Baltimore. (I know Boston has interest, but I think that their new "fiscal reality" might preclude such a deal.)
