So what's the difference between this thread and "Realistic View of 2017"?
Anyway, I don't think we necessarily need to add a bat (Hanley, Pablo, Shaw, and Holt ought to be able to fill 3 positions between them, with Moncada and perhaps Travis on the horizon), but with Papi leaving, I expect we will nonetheless. I'd be loathe to give EE a fat 4-5 year deal at age 34 and give up a 1st round pick in the process, but it's hard to see Henry & Dombrowski losing Papi and not finding a way to bring in another masher in his place.
I don't think we see any major changes to the rotation... Price/Porcello/Pomeranz/Rodriguez/Wright(/Buchholz?) is a pretty good group, though we could probably stand to add some depth beyond that.
The bullpen will be in need of a makeover, as someone else mentioned.
All in all, I expect a relatively quiet winter (which probably means it will be crazy).
