Right now, MLB transactions are frozen. Very soon, that might change. When they do, the San Francisco Giants may start to hear some trade offers.
In the past, we wrote about a couple of players they'd probably like to trade this year. (Whether they'll be able to is a totally different question.) But there are always a handful of players that could be considered untouchable -- whether because of what they mean to the franchise right now or what they can do for it in the future.
Clearly, the Giants have far more players they'd like to trade than players they'll certainly want to hold on to.
