Ben was at the helm for 2013 and he gets the credit for it. It was a perfect season almost from beginning to end. When the starters faltered, the bullpen stepped up. The starters came out of spring training on fire. Buch ignited us with 11-0 to start the season and a miniscule ERA. When the pitchers needed a big out, our fielders invariably came up with big plays. When the fielders made errors, the pitchers picked them up. If we made a base running mistake, our hitters made up for it and the players picked up Farrell every time he made a mistake.
What Ben didn't do in building the 2013 team was build a foundation of a consistently good team. People mistakenly believed that Ben had come up with a winning formula for other teams to imitate. The 2013 team was built on a foundation that couldn't support consistent success -- one of the main pitchers (Buchholz) and hitters (Victorino) have chronic injury issues. Napoli has two bad hips and his performance has been decaying for 2 seasons. He kept each of these diminishing players (in health and skill) for the next 2 years and their performances fell off a cliff. The healthy younger players from the 2013 team were allowed to walk away over the next 2 seasons -- Ellsbury, Lester, and Lackey. He let our stud horses walk and he retained the broken down war horses. He also put much too much reliance on too many unproven rookies in the following season.
Yes, Ben was the architect of 2013, but he also dismantled that team in the following year and kept all the wrong parts.
