I think Maddon would probably go with a 4-man rotaiton and obviously Davis would be out. I'm trying to remember the off-days but think you can only get away with 3-man rotaiton in the division series. In the other rounds it would require going on short rest. And while they could, there really is no reason if there isn't a big dropoff for #4. And even if the spacing works in the ALDS, I doubt JoeMa would want to risk the 4th starter going 10-12 days between starts if he isn't used in the ALDS but is used in ALCS.
