Davis was a plus defender last year (his first full year at 3rd rather than being moved everywhere). He's not IKF with the glove, but he's probably slightly above average both offensively and defensively. If he puts up last year's defense and the ~120 wRC+ he had in previous years, he's probably a 3 war player. Doesn't hurt that it's his contract year either. IMO the best way we can utilize IKF is as a later game defensive replacement / pinch runner. He has a ton of value in that role.
