Gonzalez hit .306 on the road, and .244 at home. He did that in a garbage lineup where he saw next to no good pitches to hit. He put up an OPS+ of 166, Cabrera put up an OPS+ of 142, Jason Bay put up an OPS+ of 134, OPS+ is more reliable than BA or OPS because it takes where the player plays into consideration, but even without that he still had a better OPS than Cabrera. A-Gon is the best hitter of the three, makes next to no money the next two years, is a GG first basemen, and has a swing made for Fenway, he would hit .300 with 45 HR here. The term perfect fit comes to mind and he supposedly wants to come here if he is to be dealt, but the Padres will want a ton because theres no incentive to deal him.
Also, Miguel Cabrera is a first basemen now, he is too out of shape to play 3rd, so Youkilis would have to move to 3rd if they got him too. Cabrera also makes a ton of money, and ontop of his conditioning problems there are questions about his character. If the Sox are going to deplete the farm system, id prefer A-Gon to Cabrera by a fair amount.
