Before launching further into the thought process of the bombastic heading of this post, some declarative statements need to be made. First, Roy Halladay has been a much more valuable pitcher over his career than Tim Hudson. Roy Halladay has won two Cy Young Awards and probably should have won another. Tim Hudson has never won a Cy Young Award and probably never will. Roy Halladay has accumulated ten more wins above replacement in his career according to Baseball-reference.com and twenty more according to Fangraphs. But all that being said, a lot of the same end results are remarkably similar.
