Since the beginning of 2014: Pitcher A: 75 GS, 445.1 Inn, 4.03 xFIP, 16.1 K%, 7.8 BB%, 106 ERA-, 99 FIP- Pitcher B: 78 GS, 457.2 Inn, 4.40 xFIP, 17.9 K%, 9.3 BB%, 102 ERA-, 111FIP- Which pitcher would you prefer? Pitcher A is Gibson, B is Miller. Miller has a slightly better K rate, but worse walk rate, worse groundball rate, worse HR rate, and gets to pitch in the NL. Gibson has a 69.1% LOB over the same time frame and Miller has a LOB% of 73.2. Some of that may be defense related?
