Some actual big one's on there. Furcal is one, but not really sure it matters where he plays, he'll be useful in any stadium. I wouldn't call Damon a big free-agent, simply because i don't think he's leaving Boston. If a FA isn't leaving their home stadium, doesn't really have much of an impact.
Some notables: Burnett, Clemens (Will he get a contract and be around?), Billy Wagner, Brian Giles (Big one, if he leaves SD huge value jump), Trevor Hoffman, Matt Morris, Preston Wilson... probably others, but these were the guys that jumped out when I checked the list.
...Boston papers now and then suffer a sharp flurry of arithmetic on this score; indeed, for Williams to have distributed all his hits so they did nobody else any good would constitute a feat of placement unparalleled in the annals of selfishness. -Updike
