Yes. IMO, we are good for 2019, as our team is remaining mostly intact.
We'll lose Pom, but how much did he really help us this year? With good health, our rotation is good to go. I would look for some of those dumpster dive depth pieces that everyone here loves so much.
I don't think finding quality bullpen arms should be a problem.
I guess our biggest need or question mark will be what to do about 2B. I think Pedroia will be back, but I also thought he would be back this year. Either way, the Sox need to have a viable back up plan in place. Perhaps we can make do with Holt, Nunez, Hernandez? again until the trade deadline like we did this year.
Short answer: Yes, the Sox will be a strong contender next year.
