Ok, I was wrong, Casey McGehee can play 2B. He also did not make any major mistakes at 2B in his 20 games there. However, given that a good argument can be made that he is a below average defender at 3B, an easier defensive position, and his physical limitations, there is no way he should ever be considered to play 2B, outside of videogames, except in the most dire circumstances let alone going into a season with him penciled in as the starter at 2B. I prefer my 2B to not look like they are playing defense in a telephone booth.
