Ken,
Your title says RT but your text implies you are inquiring about traditional league value. If you are a contender in a traditional league and have Bonds I think he is untouchable. On the other hand if you are rebuilding in a traditional league I think you need to trade him to a contender. What you get probably depends on your neeeds and what the contender can afford to give and will vary by team/league.

If you really did want to know about Bonds' value in RT then I think the opposite is true. Contenders should trade Bonds to get something to help this season. Rebuilding teams who will not make the playoffs might as well hang on to Bonds and see what they get next season when presumably he will be playing and healthy.
