Gonzalez, who won a Gold Glove, Silver Slugger, and finished third in the NL MVP voting, clearly has superstar written on him. But locking him up to a long-term contract will not come easy, as we saw with Gonzalez' also-Boras-client predecessor, Matt Holliday.
Holliday acquiesced to 2-year, $23M contract after the 2007 season, which took care of the remainder of his arbitration years, but no farther than that. Signing a contract that covers arbitration years isn't unheard of with Boras, but anything extending into potential free agency is something that Boras tends to not agree to.
Troy Renck of the Denver Post is reporting that talks aren't really underway yet. The Rockies have inquired into whether or not Cargo would be interested in extending. Nothing concrete yet.
