I know what your thinking Joe is the best catcher in baseball and the Twinks would be crazy to move him. He is the best catcher in baseball and handles the pitching staff marvelously. That being said catchers take a beating over the haul of 162 games and it is very hard on the knees. Moving Mauer to third would be a defensive loss yes, however I think it worth the trade off reducing injury risk. I am not writing this because I don't enjoy watching Mauer catch, I just would like to see him stay healthy for many years to come.
