Harden is an outstanding pitcher but CC does more to help his team win games.
Mariano Rivera is an outstanding pitcher but I would never rate him as a better pitcher than the better starters in the majors for major reason......

As others have pointed out withing this thread but you're too much of a tool to accept, Harden just doesn't pitch enough innings to be considered in the fashion you are attempting to.
