I would put Ozzie Guillen towards the top so far this year. Basically has the same roster as last year, Sox are towards the top in all offensive catagories.
One of the worst is Dusty Baker. He has some odd moves at times. I vote for him because of "Waving" Wendell Kim, the 3rd base coach is back. He is brutal and has cost the Cubs at least 5 runs sending players home.
