Interesting on the diffs on the injury (I see 86 days). Maybe looking at him from outside your world doesn't factor in your training and medical impact? Let's assume your number is right, so the Maxwell-Moore situation is back where it started a week from now.
I'd say Moore has to start at SS as long as his offense doesn't fall off a cliff. I like your idea of moving Maxwell around. He helps your defense at 5-6 positions (CF is arguable). "Rest time" for your COFs would be ideal when you're playing in parks which favor doubles and triples.
