Would assume Murphy is not going to be signed back unless no one else goes after him. He's a great addition to the team this year because the bats were slumping when he came in. But with his defense, he needs to OPS at .900 to be a valuable part of the team, and he hasn't been doing that the past couple of weeks.
I am still all in on trading Addy and Almora for whatever we can get, sign Harper, move JHey to center. Have an infield of Riz, Baez, Bryant and a rotation at 2nd of Happ/Bote/Zobs/TLS. Its easy - and we don't sacrifice defense really at any position - maybe Center, but JHey in center is no worse than Happ out there. We either pick up the option on Hamels (preferably) or go with our internal options at the 5 spot - Lester is back, and he isn't Jon Lester anymore, but he's good enough, Hendricks, Q, Yu all back - with MiMo still on the roster if he isn't traded too, and Drew Smyly. Pen should be fine with only losing Wilson and midseason pickups Chavez and De La Rosa. Would assume Stropy has his option picked up, Morrow is back, Kintzler is back (unfortunately), CJ still here, Chatwood (unfortunately) - with the shuttle of Maples, Bass, Rosario, Mekkes all getting shots to fill the other 2-3 or so positions unless they want to upgrade here.
Q and Hendricks have both pitched well the last month or so and starting to look like their old selves. Pitching and defense wins championships - with a healthy Riz/Bryant and potentially Harper, this team would come back as the likely favorites in the NL next year.
