I disagree.You don't travel to major tournaments just to play in front of coaches. You travel to major tournaments to play great competition. That's how kids get better, playing better competition.
Take 1 kid out to a field down the street and work with her and only her for 2 hours.
How many ground balls can she field? How many at bats can she have?
A pile of each if she's in shape and she hustles.
Now take the same kid 3,000 miles from how to play 5 games.
How many ground balls will she likely field? How many at bats will she likely have?
Best case scenario is roughly 20 at bats. If she made a play every inning she played she would field 35 balls.
