The settings captaincoop are solid. Personally, I like development to get a little boost.
Batter Dev. at 1.200 and Pitcher Dev. at 1.100 are settings I'm comfortable with. Teams that are rebuilding get a little boost timewise in the development of its spects: alway a good thing for those that have struggled with their teams or are taking over a franchise in poor shape.
captainc has presented settings i would be comfortable with.
