I think I would gamble as my third OF. The way 12 man teams are going these days there are a LOT of OF left I would not mind taking off the FAs (Green, Alou, Drew sometimes).
So I figuire, if Bonds dies, or umm, you know, injures himself again, I have many options. Better yet take him as your utility as there are MANY guys on the FAs that could prove to have great years (Kotchman, Fielder, etc...)
Sean Tracey has my apologies, we all know Ozzie Guillen is an idiot. I'm rooting for you!
