Bleacher,
I agree about TLR sooner is better than later. I want a decision, even if it isn't the decision I would prefer.
IMO Oquendo is definitely the favorite for the managers job. Some other options would be Girardi or Pena. I'm sure there are a couple of more people in our organization that deserve a look also.
The following is more for entertainment than practicallity.
As for replacement Pitching Coaches, I don't really have enough knowledge to make an educated choice. I'm guessing our minor league guys would be worth a look. Or how about Matheny (long shot considering the lack of experience).
Hitting coaches (this could be fun); Will Clark, Mark McGwire, Larry Walker, Willie McGee, Rick Eckstein, how about Tony Gwynn, of course I'd always bring back Mitchell Paige (Rolen, Edmonds, and Renterria all had career years under his tutilage, he must have been doing something right).
Your Base Coaches; You could take a few guys from above and insert them at the corners.
Remember this is just for fun, but how about the following;
Manager- Oquendo
Bench Coach- Ozzie Smith/Willie McGee
Pitching Coach- Matheny
Hitting Coach- Tony Gwynn
1st Base- Larry Walker
3rd Base- Will Clark
Could you imagine the first time a player look at a coach and said "Hey, what do you know?"
