I don't have a link- just saw this on the show I know there have been a thousand of these "rumors", but I thought this one was worth bringing to your attention, to help keep a running count. The context was a discussion of players generally "available" or unavailable, and after discussing Sanchez as generally available, Jon Heyman said "there are GMs out there" that have said that Matt Cain may "become" available too. I suppose the "sources" could be the scurrilous rumors already posted here, but passing it along for whatever it's worth.
