A few thoughts:
1) If we don't win the World Series this year, Dusty will clearly be gone. But if we do, I'm a believer in the MJ doctrine that if you win a title, you have the right to defend it. Winning back-to-back titles is soooooo difficult. It would likely be a once-in-a-lifetime thing for most of us.
Maybe Dusty would make it easy on us and voluntarily hang it up. Going out on top as back-to-back champs seems like a nice option for him. But if he really wants to come back and go for three, I'd error on the side of letting him. Looking forward to hearing everyone adamantly agree with this take.
2) For next year, I really like the Diaz plan of 100 games behind the plate, 25 at 1B and 25 at DH/LF. That leaves 62 games behind the plate. I think Maldy is perfect for a part time role. Keep him in the clubhouse. Let him be JV's personal catcher and sprinkle him another game per week. In September, evaluate how JV is doing. If he's pitching like an ace, consider letting Maldy continue catching him into October. If JV is good but not great, Diaz catches him from September on.
3) On the bullpen front, I like the idea bringing back Neris or adding Hader. Then we've got our allotment of high lev guys. Assuming our staff can generally stay healthy next year, I think we'll eat alot more low/med lev bullpen innings with starters-not-in-the-rotation. The fact that we couldn't do that much this year cuz of the injury bug hurt badly in terms of keeping the staff fresh.
