You're not going to get anyone of Greene's level for just Marmol straight up. Again, unless it looks like he can be stretched into a starter, as good as he is, he's still just a reliever. He can help push a deal to completion in abi way, but he's not going to be the main part of the deal. And the others I mentioned? Murton is stuck as a man out of place, yet he's a great trade piece, especially with the Padres, who have shown interest in him. Cedeno would have to go becase the need the SS depth with Greene going, and the Cubs could handle that easily wih Greene coming back in return. I'd trade Marshall or Gallagher as the final part...I could really go either way. Bottom line, you're not going to get a quality and valuable player like Greene for nothing. You're severely overvaluing Marmol. i suspect a lot of trade partners would severely overvalue marmol, however. but likely not kevin towers, since he's smart. Even by those that would overvalue him, he's still better served as part of a trade than for anything straight up, short of the rare miracle deal falling right in the Cubs' lap. "Our best reliever" is still just a reliever. It would be a diferent matter if the Cubs clearly had a crappy bullpen besides Marmol, but they don't. It's much easier to fill a bullpen with passable or better players than it is to seriously upgrade at a position spot...and Marmol has the shine to be a big part of a deal to do so, and the Cubs have the luxury of parting with him. A reliever right now, even one as good as Marmol, IS a spare part, and one that can ad should be traded for maximum value. Not that it matters. Hendry never sells high. He's gonna glom onto Marmol because the fans love him and relegate him to the closer role after Wood breaks down for good this year or the next.
