The problem with "inside" information, of course, is that when someone says that a player "may" be traded, or something else that is somehow conditioned, well ... obviously there is no way to show it is or was wrong. As a result I'm extremely skeptical about such things unless there is very tangible evidence of the nature of the "inside" information.
As to the possibility of a specific Barney trade, how many people within the Cubs organization would actually know that at this point? I doubt it would be more than a handful, if that many. I think there was real evidence that other teams wanted Barney last year, and that the Cubs have no particular interest in trading him - unless they were to get a a very substantial return. So I'm skeptical.
Perhaps I'm wrong, but it seems like I recall both of those guys saying something definitive was going to happen in a trade or signing that never did.
On the other hand, I suppose it's possible that one or both does have inside information. I don't think there will ever be any way to prove either possibility. And it's always fun to speculate this time of year.
