Josh was the first pitcher in 2 years to win 20 games. He had a higher ERA than Sabathia, though, and all that jazz. I'm sure if you were someone other than me and inclined to break out a calculator and do some, you know, actual in-depth research about this, you could come up with an argument showing Josh was statistically luckier than Sabathia, adjust for defense, etc.
I really wanted Josh to win, just because essentially the more acknowledgment there is about the superiority of the Boston Red Sox in the wider world, the better. But the bottom line is, CC Sabathia lost something much more valuable to Josh this season than Josh lost to him, and I'm sure he'd trade in a heartbeat.
