So, to sum up: Positives: Age, Injury History, Plate Discipline, Power, Covers a position of need, Left-handed Negatives: Baserunning, Fielding, Body Type The primary question becomes do you accept the positives over the negatives, and for how long? For me, offensive ability like Fielder's comes at a premium, and as long as he can keep that up and stay healthy, he should be paid a premium to produce it. I'd love to get away with a 5 year deal, and 6 would be satisfactory. The problem with the Cubs right now, in my opinion, is they have a complete dearth of options at 1B internally for the next several years (I mean, it's what, Vogelbach possibly, Vitters maybe, or else they'd better start drafting players that have a bat that can stick at first). The options they're left with is to see if they can get value in a trade for somebody like Logan Morrison and hope he pans out, or pick up Daric Barton if the A's drop him and see if his last year was a fluke (and is also just one year younger than Fielder). Both of those options have more questions than Fielder does, and it's not always about getting the most value efficient team, it's about getting the best team, and Fielder is easily the best option available for at least the next four years.
