I think Porcello will be lucky to return to his career norms in 2016. He's just not a top of the rotation pitcher. He is a 4 or 5. The pitch selection argument is bogus imo. His fastball velocity was up, and it was getting hit hard, because he wasn't commanding the pitch. That is execution. Just because his FB velocity was up from prior seasons doesn't mean that he didn't have an injury. Many feel that loss of command is the first sign of an injury, and he was DL'd during the season. It could also be that he couldn't harness the command of his increased velocity. If he vastly improves in 2016, it will be because he learns to harness command of his higher velocity, not because of the mix of his pitches. He left too many fastballs dead red for hitters.
