Personally, if we acquire a #2 SP and one of 1B, 2B, 3B, I'd be good with going with an internal option at the other infield positions. That send, I do think the Red Sox should be willing to go over the luxury tax limit this offseason if the right moves present themselves.
I would take a flier on Kelly for 1 or 2 years, maybe 3. I'm not sure he's the strong #2 that I'd like, but he's at least a strong #3. And he's been relatively durable.
I'm still not happy about the idea of trading Duran, or any of our outfielders, for that matter. But if it must be done, I'll survive.
