There is a kid from around here named Corey Ray. He is by what anyone would define as a natural athlete. Coming out of high school he was a 6.7 sixty runner, fast twitch athlete, super quick. Played for Louisville in college. Drafted in the 1st Round, now in the Brewers organization.
That kid worked on Baseball all the time. Could he have made it to D1 just on high school activities and travel ball experiences? Probably, but no way would he have advanced as far as he did without a ton of extra work.
Look at Hunter Greene. I bet if all Hunter did was team practices he'd still throw 90. He is taking his game to another level. Some kids want it more than others.
"Lazy" is relative. Yeah, any kid playing high school Baseball is not lazy compared to the fat kid sitting on a couch eating Doritos. And not every kid who works night & day is going to play D1 Baseball, but again my point is that any kid with a modest amount of athletic talent can work their way into having at least a role playing spot on a high school team. It is how much they want to work at it.
And the work ethic is the reward, ultimately. It carries over to the rest of life.
