Thanks...but ...when you say you don't 'think' they do much, you mean you've observed the difference as not much or you have watched hours & hours of replay and clearly don't see the hit & run being put on more or less often depending on where you have it set.
Because I remember I had Brett's set just one notch high and he hit & run with terrible results in a playoff game, where the runners took off and the outfielder made an outstanding catch and doubled up not one runner off the bag but...TWO. I would have won that game if the ball dropped in, too (
)....and it was sort of an accident that Brett's hit & run slider was notched up.
