I'm the last person who would trade prospects, but Fielder's only 26, he's a proven commodity, if he can be resigned for at least 5 years, the White Sox should consider it. I imagine the Brewers would want either Viciedo or Flowers as the centerpiece in the deal, a replacement level player to take over first base. They'll want at least two pitchers, possibly three and one or two position players. You're looking at sending them five players for Fielder. Fielder isn't a free agent until after 2011, so they would be need to be overwhelmed.
