I agree that it's incredibly unlikely that it would actually work, but if he's not dealt at the deadline, then there's really no reason not to try him out there. As unlikely as it is, there's still a non-zero chance that it works and when the other options are to bench him, delay Rizzo, or move Rizzo to another position, the only logical choice is to see if he can do it. Well, I think the difference is some see it as moving him there to make room for Rizzo, not "we have to find room for LaHair!"
