If everything didn't go right in 2013 and the team went a pedestrian 81-81, I wonder if things would have played out differently with Ben. The moves on paper suggested it was a "bridge" year. Had it played out that way, 2014 would have been more of the same and there probably wouldn't have been a pressing need to sign Sandoval or Hanley in 2015 because people would be buying into the youth movement. I think 2013 changed peoples expectations. Overall, he was a pretty poor GM. Most of the prospects he should get credit for are still a few years from contributing and still in A ball, Benintendi excluded. He could take credit for EdRod but that was a trade and I'm not sure if Boston should get credit for developing him or Baltimore. The only really big contributors he was responsible for bringing to the 2016 team is Rick Porcello and some of the bullpen (Koji, Layne, Ross, Hembree). Hanley Ramirez too, though he could probably be replaced for a fraction of the cost.
Also his 2012 and 2013 drafts are looking terrible. 2014 looks like it could be promising, but Kopech has make up issues, Sam Travis doesn't have a really high ceiling, and Chavis and Ockimey have strike out concerns. Good news about Chavis is he's cut his strike out rate from 31% last year to 13% this year, while Ockimey has went from 34% to 23% while moving up leagues. 2015 it's too early to tell but bNES alone will probably make it a success Of the 2012 class, you can still hope Pat Light and Brian Johnson can offer something and Marrero looks like a career UT. The 2013 class has Trey Ball who has been a huge disappointment but is still too young to write off, picked up Dubon (another possible career UT guy) in the 26th round and Nick Longhi in the 30th. Longhi is only 20 and holding his own in Salem. It's still too early to tell, but they may need Longhi to save this draft. Carlos Asuaje will probably have a major league career of some sort too, even if it's just a cup of coffee. Joe Gunkel as well.
Of course he is also responsible for Moncada, the Basabe twins, Espinoza, Raudes, and Devers. Moncada, Devers and Espinoza are well documented but Raudes is only a few months younger than Espinoza and putting up similiar performances and Luis Alejandro Basabe is hitting the quietest .313/.414/.467 a 19 year old in Greenville could possibly hit.
