That's big hole there, and I think the writer's belief that manager's won't exploit it is misguided. I don't think they'll have it as obvious as walking to next to second and dropping it, but I could see them making their outfielders intentionally drop it by looking unintentional to cause confusion, either out of exploitation or to bring enough attention to it so the league will change it ASAP.
Hopefully this gets changed before next season. Can you imagine how tainted the World Series would be if something like this lead to a defining outcome? Obviously it will be fixed by the next year, but that would do some serious damage to the league overall.
