I disagree with that description of Davis' defense. I know that Buck speaks very highly of him at 1B, so maybe I'm way out on a limb, but I think he's just OK at 1B. Good range, great arm, but only ok at scooping throws and flat out bad at fielding ground balls.
He hasn't played outfield much, and has looked bad at times when he's been out there, but I think he's shown some flashes of being able to use his athleticism and arm out there. I really think if he was a full-time outfielder that he would end up being well above average in RF. As good as anybody out there aside from the handful or so of newly converted CF who still have great range which there always seems to be.
We will have to disagree, I think Davis is a really good first baseman. His ability to scoop bad throws is run saving by itself, and I am not sure there is a better throwing first baseman in the game.
As for RF, is he better than anyone we had, sure, but our right fielders stunk, until Bourn got here.
