In the fall even when we were running out of sun, we still got BP (all three pitchers in) and two different fielding drills in, so not sure what you are talking about. It does not mean take 10 whacks while others watch.
My team lost a few games (other issues) but we put up the most runs of any other team in tourneys except for the winner (public record) and my team record of an exceedingly high batting average.
Not sure how pitchers or hitters can be good in games when they never practice that level of intensity, unknown situations, visual distractions, etc. in practice.
You have ONE pitcher and ONE batter involved in that unless the batter hits the ball. So you are telling me that your hitters hit EVERY pitch? Well, if they don't everyone else is just standing around.
