Every school playground in my town has a backstop and diamond that neighborhood kids can access if they want to. But the only guaranteed time fields are used is at recess, when schools permit kickball, but ban hardball (too dangerous).
The point of this initial discussion was that big leaguers -- at least the ones we root for -- look more inept at basic fundamentals that came as second-nature in the past -- and maybe that's because ballplayers once grew up spending more time playing more various forms of baseball (and not necessarily in complete, organized 9-on-9 games in uniform, run by adult coaches... and don't get me wrong, I coached high school for a decade, and now my son's Little League in fall, spring, and summer All-Stars -- and, we also pay for him to play travel ball; the more baseball, the better).
