CS rate has a lot more to do with the pitcher than the catcher. Trying to infer anything about Navarro's arm based on CS% in backup catcher innings wouldn't be wise.
Things should be better with Cobb and Smyly back next year. Those two with Odorizzi and Archer should be legit, and Moore, Karns, and Guerrieri can fight for the 5th spot.
Anyone want Cal Cluttetbuck? I don't care enough about this league to do any math, but 300+ hits might make him reasonably valuable. Or maybe not, I dunno.
I think you're drifting closer and closer to a rebuild season. No picks or prospects, and your entire team except Hosmer, Grandal, Pollock, and Harvey will be 30+ next year.
