gotta disagree a little here. correct to some extent, but there are lots of interdepencies in softballOn a serious note the only thing you should require from a player is that they are not a disruption so that any player feels uncomfortable to the point
where it effects their play. Softball is not a team sport in the way basketball or football is..you don't have to pass to anybody or block for anybody. Each player has to win their individual "battle" (whether it be with the pitcher,batter, ground ball, fly ball,etc). Outside of the occasional sacrifice bunt, what is good for the individual is good for the team. If a player cannot manage that requirement then they can be shown the door..
P/C . . this could be a entire thesis
IF/1B . 1B has to trust that fielders are going to try to make the best throw they can . . . IF needs to trust 1B to will do their utmost to erase their mistakes (ie non ideal throws)
P has to depend that if she makes a mistake, everyone behind her is busting their rear to mitigate it, not just making average effort because, hey, they didnt give up that shot to the corner.
batter/baserunner . BR has to know that on a hit and run situation, batter is doing everything in their power to put the ball in play, or at worst foul it off.
C / MI catcher has to believe that MI will field a not perfect throw cleanly and still apply tag, and has to depend on OF to be calling out loudly when the runner goes.
General, when someone calls everyone else off, they all have to believe it was because the player calling felt they had the best angle/shot at it.
