I don't know about Giambi...he wasn't that bad for that long like Jones was, and, although he's putting up pretty decent production as far as 1Bs go, he's not one of the most dominant at his position this year. Jones went from 4 years of garbage to being perhaps the most dominant reliever in all of baseball this year. The big difference is that jason played in Ny where everything is analyzed and the pressure is ten times any other city and 100 times that of what Jones who played in pitiful Florida (pitiful, refering to the fan support or the media support)
