The linked article cites this blog post in which a Padres observer suggests the Phillies would be willing to trade a top-50 overall prospect, Jonathan Singleton, for Mike Adams. The article linked in the title of this fanshot then proposes that Marshall is actually a better reliever than Adams, and that Singleton might be only the lead prospect in a deal.
I link to this proposal not because this is any sort of a done deal, but it seems like an interesting test case for our fan discussion of what the Cubs should be doing in the trade market right now. When some have proposed trading Marshall, others have said, "For what?" What if the answer is "for the recent World Champions' #2 prospect, with the best plate discipline and power in their system, and who's only 19 and succeeding in high-A ball...plus a relief prospect?"
Trading for such a young player obviously would not help the major league club for the next few years. Would such a trade be worth it, in your opinion?
