misunderstood

[clueless]

I'm speaking as a coach. But last year, I saw these area cause some confusion:

Infield fly rule

obstruction/interference rules

over running first base rules (with regard to committing yourself to one bag or the other)

Look back rule

courtesy runners

substitutions/rentry

dropped 3rd strikes

Those are areas that stick out that I saw giving some coaches and players problems. Many of my peers do not do their study and research. Thus, they tend to be in the dark about a lot of stuff.
