When was the last time the Giants made a blockbuster-type trade in which they traded away a star to get prospects? Please tell me it wasn't the Matt Williams trade 15ish years ago! Looking at the Rockies this season, it's clear that a key to their success this season was by trading away Matt Holliday and getting Huston Street and Carlos Gonzalez in return. The Giants need to fill multiple holes in their lineup, and after trading away Barnes and Alderson, their stock of pitching prospects ready to contribute is suddenly thin. Given the rumors that the Brewers are dangling Mat Gamel, I'd like to see the Giants trade Matt Cain for Gamel, Jeremy Jeffress (top pitching prospect) and maybe even JJ Hardy or another major league throw-in player in order to retool in multiple areas.
Sabean probably doesn't have the balls to do such a thing, but a "rebuilding" trade is just what the Giants need to win the division next year.
