I think Gardy is a pretty bad manager, but this isn't the reason why. Like others said, given range factors at TF, you want your best defenders in left and center. Add to it, that Revere's arm is bad on so many levels. You don't put that in right, as people will be going from first to third all day long on pitches hit to right. Like John, I'm not getting the consternation of switching Willingham from left to right. It really isn't that much different of a position, and using Delmon as a comp is kind of foolish. Delmon is a bad defender anywhere in the OF. That has to do with his size and the fact that he doesn't get good reads on the ball. That doesn't change in RF, the only difference is that he would have had less plays to screw up out there. As for what's best for the team... Span is a plus defender in center. I agree that Revere may have better range, I don't agree that this means he should be in center (just a caveat to this, but I don't think he should be playing every day, but that's a separate issue). Again, with his arm, it makes more sense to put him in left where the weak arm is protected. As with right, you'll see plenty of people going first to third with anything hit reasonably well to center. Last year, we got to see a non-burner runner tag from second to home on a sac to center. How often do you see that when there's no error on the play? This isn't a situation where putting Revere in center is clearly best for the team. Doin't so consistently will probably lead to an extra out every week or two. That move makes sense in late innings when protecting a small lead with no runners on, but not so much otherwise.
