Even if he did try to bunt, teams aren't going to immediately go back to playing normal, and the trade off of Dunn trying to make an attempt at a bunt(which Im sure he hasnt done much of) and him hitting the ball 400 feet, Id take every day. It would take him going up there pretty much every at bat for multiple games before teams would consider changing their defense, and if he wants to do it 3 or 4 times a game, well Ill gladly take it opposed to the alternative.
