i am not questioning your statistics. They are just not an excuse for Porcello's or the team's performance. It would be like a lawyer defending his client against an assault charge be arguing to the jury that his client missed his morning coffee, missed his train and was going to be late for work and would lose his job as a defense for slugging the victim when he bumped into him. All the fact are accurate, but the defense isn't valid.
Porcello is not a victim of bad defenses and worse luck on both the Tigers and the Red Sox. As pointed out, Verlander, Scherzer, Anibel Sanchez, and Doug Fister all had success with the Tigers. Porcello was the #4 guy on those staffs because that is where he belonged. They all had the same team behind them.
