Ya not much of a debate. Bumgarner has done it on the biggest stage in baseball. Basically carried us to a World Championship last year, and shined as well in our other 2 postseason runs. Not even close. Has Greinke even won a playoff game? Hard for me that people say Kershaw is a better pitcher than BumGarner. The best players step up on the biggest stage against the other great players. Kershaw does nothing in the postseason. Kind of like people used to debate Manning or Brady, not even close. Brady owns him and the postseason. Who cares what you do in the middle of the season against the Marlins or the Jax Jaguars. What do you do against other elite competition in the playoffs. Just my opinion.
