Well, the Cubs are basically requesting of teams that they "take whatever they want'' when it comes to a potential Samardzija deal.
That may be a slight exaggeration, but not much.
The Cubs like Samardzija (6-9, 3.94 with more than a strikeout an inning) so much that it's hard to see them doing a deal. The only reason they're looking around at all is that Samardzija has shown little interest yet in doing a long-term deal, at least not one in the ballpark of what the Cubs offered.
Another thing they love about Samardzija is his supreme confidence, which is manifested in his reluctance to sign an early deal. He loves Chicago (he's from northern Indiana) but he also apparently relishes the idea of free agency after 2016.
The Diamondbacks are one team that's shown interest in Samardzija, but there are apparently several others.
The Cubs are by far the clubhouse leader in trades already (Matt Garza, Alfonso Soriano, Scott Feldman and Carlos Marmol are among the departed), and they have gathered an impressive collection of young players, particularly taking advantage of Matt Garza's hot streak to turn him into a very nice package, leading with pitcher C.J. Edwards and third baseman Mike Olt.
But they stil have work to do. They are talking to teams about outfielders Nate Schierholtz (though they have him for another year) and David DeJesus, catcher Dioner Navarro and pitchers Kevin Gregg and Carlos Villanueva.
