Notice where most those deals come from? Besides the Yanks, it's all pretty much big market clubs outside of maybe Cleveland. Phillies won't need Bay, neither will LAD. LAA, NYM, NYY, and Boston are his likely landing spots.
As I said before there are only a few teams that can offer these large deals. The Sox are trying to stay away from handing them out, except for top tier talent. Tex was that. Bay is good, but he's not a premier bat in the league. Although the Yankees may pay Bay like one, but that's because they don't care how many zero's are in the deal, just as long as there is an AS at each position:D.
NYM, Bos, NYY, LAA are the only teams that can offer Bay 15M+ a year. Maybe LAD if they found some way to rid themselves of Manny, but I think there stuck with him. Every other team in the league is watching payroll closely, trying to get younger and cheaper. Add a big contract like Bay just doesn't seem like a great business move for most teams is really all I'm trying to say.
I see the Sox offering somewhere around 12-15M a season. If he doesn't except that, he will most likely be a Yankee, because I don't see any other team offering more then that besides them. Other teams will be interested in him, but if that yanks want him, they will get him.
