The difference between the Goldy contract and the upcoming Freeman extension is, the Braves will likely have the luxury of the DH for the entirety of Freeman's remaining years.
Honestly the possibility of the DH doesn't really do much for me regarding a Freeman nor should it be any other team really. He's a good 1B and I doubt he's ever going to be Ortiz bad out there where actually playing him will be a detriment to your defense. It's all about hitting. And I don't think being a DH some days would really save his bat so to speak. Much better hitting 1B than him have fallen hard in their 30's that have had the benefit of the DH.
It's going to be hard for AA to go more than 3 years when he knows how players like Freeman usually age. And it's going to be hard for Freeman to only accept a 3 year deal when he knows some team will likely give him the moon.
