Well he switched to 1B mostly because of his decline in ability to play RF. That switch in and of itself has caused a decline in his value. He will probably be a 2.5-3 WAR player this year. That's a decline and its played out right in front of us so I don't know how you can't see it. In addition, we've seen him just "lose it" for more than just a bad month or two. Fair or not, that's always going to stick around in the back of people's minds. I've said it before, and I'll say it again... I really don't think Hart is that bad at all in RF, especially when watching some of the guys that other teams put out there. I saw the reason for the switch to 1B more to take over for Green/Ishakawa who were dreadful/hurt, while opening up a regular role for Aoki. We aren't going to agree on his defense then, but then I'll just say that if other GMs feel the way you do, Hart has more value to that team and should be traded.
