i dont think speeches mean much of anything to players at this level. tactics, yes. teaching, probably. in game decision making? a bit.
all in all, managers can make a small difference over the course of the long season, but have more of an influence in a short series playoff. managers. as with all sports, the most important thing is talent and its acquisition and development.
you know how i feel about it, but its a results oriented business. and the results have been pretty poor. so you cant really say anyone in management has done a good job, from avila to hinch to the bat boy.
