Felix has to face the Rangers, so your point goes both ways. In fact, I find it all the more impressive that he didn't get discouraged from one of the worst offensive teams of our time, and continued to go out and shut down the opposition.
Also, if what you say is true, then what about Cliff Lee's amazing Cy Young year? How about Zack Grienke's season from last year? Their teams didn't give them a chance to play in meaningful games because they were so abysmal. I disagree with you totally, because the best pitcher shouldn't be decided on whether or not his team was any good. It's not the Most Valuable award for a reason, bc it's not value-based, it has nothing to do with the team getting into the postseason. But, to each their own.
